-## Migration Procedures

- :::image type="content" source="./media/retention-migration/diagnostics-setting.png" alt-text="A screenshot showing a diagnostics setting page.":::

-For example, for *all* insight activity logs, use the container *insights-activity-logs* to set the retention for all of the log in that container logs.

- The example below shows the prefix for a specific web app: **insights-activity-logs/ResourceId=/SUBSCRIPTIONS/d05145d-4a5d-4a5d-4a5d-5267eae1bbc7/RESOURCEGROUPS/rg-001/PROVIDERS/MICROSOFT.WEB/SITES/appfromdocker1*.

- To set the rule for all resources in the resource group, use *insights-activity-logs/ResourceId=/SUBSCRIPTIONS/d05145d-4a5d-4a5d-4a5d-5267eae1bbc7/RESOURCEGROUPS/rg-001*.

-Use the [az storage account management-policy create](/cli/azure/storage/account/management-policy#az-storage-account-management-policy-create) command to create a lifecycle management policy. You must still set the retention in your diagnostic settings to *0*. See the Azure portal section above for more information.

- "insights-activity-logs/ResourceId=/SUBSCRIPTIONS/ABCD1234-5849-ABCD-1234-9876543210AB"

-Apply the following template to create a lifecycle management policy. You must still set the retention in your diagnostic settings to *0*. See the Azure portal section above for more information.

-The following template sets the retention for storage account *azmonstorageaccount001* for all blobs in the container *insights-activity-logs* for all resources for the subscription ID *ABCD1234-5849-ABCD-1234-9876543210AB*.

- "insights-activity-logs/ResourceId=/SUBSCRIPTIONS/ABCD1234-5849-ABCD-1234-9876543210AB"

-This article shows you how to create a Log Analytics workspace. When you collect logs and data, the information is stored in a workspace. A workspace has a unique workspace ID and resource ID. The workspace name must be unique for a given resource group. After you've created a workspace, configure data sources and solutions to store their data there.

-You need a Log Analytics workspace if you collect data from:

-* Azure resources in your subscription.

-* On-premises computers monitored by System Center Operations Manager.

-* Device collections from Configuration Manager.

-* Diagnostics or log data from Azure Storage.

-* See [Collect Azure service logs and metrics for use in Log Analytics](../essentials/resource-logs.md#send-to-log-analytics-workspace) to enable data collection from Azure resources with Azure Diagnostics or Azure Storage.

-For HTTP/2, the max length for a single header is **4 K**, so if using browser to access Azure service, there will be an error `ERR_CONNECTION_` for this limitation.

-For HTTP/1.1, or C# clients, the max URI length is **12 K**, the max header length is **16 K**.

-With SDK version **1.0.6** or higher, `/negotiate` will throw `413 Payload Too Large` when the generated access token is larger than **4 K**.

-* ASP.NET "The connection isn't active, data cannot be sent to the service." error [#324](https://github.com/Azure/azure-signalr/issues/324)

-* "An error occurred while making the HTTP request to `https://<API endpoint>`. This error could be because the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This error could also be caused by a mismatch of the security binding between the client and the server."

-Check if your client request has multiple `hub` query strings. `hub` is a preserved query parameter and 400 will throw if the service detects more than one `hub` in the query.

-For security concerns, extend TTL isn't encouraged. We suggest adding reconnect logic from the client to restart the connection when such 401 occurs. When the client restarts the connection, it will negotiate with app server to get the JWT token again and get a renewed token.

-For ASP.NET SignalR, when the [client connection drops](#client_connection_drop), it reconnects using the same `connectionId` for three times before stopping the connection. `/reconnect` can help if the connection is dropped due to network intermittent issues that `/reconnect` can reestablish the persistent connection successfully. Under other circumstances, for example, the client connection is dropped due to the routed server connection is dropped, or SignalR Service has some internal errors like instance restart/failover/deployment, the connection no longer exists, thus `/reconnect` returns `404`. It's the expected behavior for `/reconnect` and after three times retry the connection stops. We suggest having [connection restart](#restart_connection) logic when connection stops.

-The connections include both client and server connections. check [here](./signalr-concept-messages-and-connections.md#how-connections-are-counted) for how connections are counted.

-When there are too many client negotiate requests at the **same** time, it may get throttled. The limit relates to the unit counts that more units has a higher limit. Besides, we suggest having a random delay before reconnecting, check [here](#restart_connection) for retry samples.

-Logger categories for Azure SignalR always start with `Microsoft.Azure.SignalR`. To enable detailed logs from Azure SignalR, configure the preceding prefixes to `Debug` level in your **appsettings.json** file like below:

-* When the server connection, which the client routed to, drops, see below section for details on [server connection drops](#server_connection_drop)

-It might be caused by improper usage of client connection. If someone forgets to stop/dispose SignalR client, the connection remains open.

-### Possible errors seen from the SignalR's metrics that is in Monitoring section of Azure portal resource menu

-SignalR client connection's `DisposeAsync` never be called, the connection keeps open.

-This issue often occurs when someone establishes a SignalR client connection in an Azure Function method instead of making it a static member in the function class. You might expect only one client connection to be established, but instead you see client connection count increase constantly in metrics. All these connections drop only after the Azure Function or Azure SignalR service restarts. This behavior is because for **each** request, Azure Function creates **one** client connection, and if you don't stop client connection in the function method, the client keeps the connections alive to Azure SignalR service.

-When the app server starts, in the background, the Azure SDK starts to initiate server connections to the remote Azure SignalR. As described in [Internals of Azure SignalR Service](https://github.com/Azure/azure-signalr/blob/dev/docs/internal.md), Azure SignalR routes incoming client traffics to these server connections. Once a server connection is dropped, all the client connections it serves will be closed too.

-As the connections between the app server and SignalR Service are persistent connections, they may experience network connectivity issues. In the Server SDK, we have an **Always Reconnect** strategy to server connections. As a best practice, we also encourage users to add continuous reconnection logic to the clients with a random delay time to avoid massive simultaneous requests to the server.

-Regularly, there are new version releases for the Azure SignalR Service, and sometimes the Azure-wide patching or upgrades or occasionally interruption from our dependent services. These events may bring in a short period of service disruption, but as long as client-side has a disconnect/reconnect mechanism, the effect is minimal like any client-side caused disconnect-reconnect.

-For ping timeout, it might be caused by high CPU usage or thread pool starvation on the server side.

-Normally, this scenario is caused by async over sync or by `Task.Result`/`Task.Wait()` in async methods.

-Then, check your log when the server connection is disconnected by ping timeout.

->[! WARNING]

-Please be advised that any information provided on the command line or as part of a URI may be logged as part of Azure Container Registry (ACR) diagnostic tracing. This includes sensitive data such as credentials, GitHub personal access tokens, and other secure information. Exercise caution to prevent any potential security risks, it is crucial to avoid including sensitive details in command lines or URIs that are subject to diagnostic logging.

-An account administrator without the service administrator or subscription owner role canΓÇÖt cancel an Azure subscription. However, an account administrator can make themself the service administrator and then they can cancel a subscription.

-description: Describes how to prepare for the retirement of the Co-Administrator and Service Administrator roles and how to remove or change these role assignments.

-> Classic resources and classic administrators will be [retired on August 31, 2024](https://azure.microsoft.com/updates/cloud-services-retirement-announcement/). Starting April 3, 2024, you won't be able to add new Co-Administrators. This date was recently extended. Remove unnecessary Co-Administrators and use Azure RBAC for fine-grained access control.

-Microsoft recommends that you manage access to Azure resources using Azure role-based access control (Azure RBAC). However, if you're still using the classic deployment model, you'll need to use a classic subscription administrator role: Service Administrator and Co-Administrator. For information about how to migrate your resources from classic deployment to Resource Manager deployment, see [Azure Resource Manager vs. classic deployment](../azure-resource-manager/management/deployment-models.md).

-If you still have classic administrators, you should remove these role assignments before the retirement date. This article describes how to prepare for the retirement of the Co-Administrator and Service Administrator roles and how to remove or change these role assignments.

-Will Co-Administrators and Service Administrator lose access after August 31, 2024?

-What should I do if I have a strong dependency on Co-Administrators or Service Administrator?

-## Prepare for Co-Administrators retirement

-If you still have classic administrators, use the following steps to help you prepare for the Co-Administrator role retirement.

-### Step 1: Review your current Co-Administrators

-1. Sign in to the [Azure portal](https://portal.azure.com) as an [Owner](built-in-roles.md#owner) of a subscription.

-1. Use the Azure portal or Azure Resource Graph to [list of your Co-Administrators](#list-classic-administrators).

-1. Review the [sign-in logs](/entra/identity/monitoring-health/concept-sign-ins) for your Co-Administrators to assess whether they're active users.

-### Step 2: Remove Co-Administrators that no longer need access

-1. If user is no longer in your enterprise, [remove Co-Administrator](#remove-a-co-administrator).

-1. If user was deleted, but their Co-Administrator assignment wasn't removed, [remove Co-Administrator](#remove-a-co-administrator).

- Users that have been deleted typically include the text **(User was not found in this directory)**.

- :::image type="content" source="media/classic-administrators/user-not-found.png" alt-text="Screenshot of user not found in directory and with Co-Administrator role." lightbox="media/classic-administrators/user-not-found.png":::

-1. After reviewing activity of user, if user is no longer active, [remove Co-Administrator](#remove-a-co-administrator).

-### Step 3: Replace existing Co-Administrators with job function roles

-Most users don't need the same permissions as a Co-Administrator. Consider a job function role instead.

-1. If a user still needs some access, determine the appropriate [job function role](role-assignments-steps.md#job-function-roles) they need.

-1. Determine the [scope](scope-overview.md) user needs.

-1. Follow steps to [assign a job function role to user](role-assignments-portal.yml).

-1. [Remove Co-Administrator](#remove-a-co-administrator).

-### Step 4: Replace existing Co-Administrators with Owner role and conditions

-Some users might need more access than what a job function role can provide. If you must assign the [Owner](built-in-roles.md#owner) role, consider adding a condition to constrain the role assignment.

-1. Assign the [Owner role at subscription scope with conditions](role-assignments-portal-subscription-admin.yml) to the user.

-1. [Remove Co-Administrator](#remove-a-co-administrator).

-## Prepare for Service Administrator retirement

-If you still have classic administrators, use the following steps to help you prepare for Service Administrator role retirement. To remove the Service Administrator, you must have at least one user who is assigned the Owner role at subscription scope without conditions to avoid orphaning the subscription. A subscription Owner has the same access as the Service Administrator.

-### Step 1: Review your current Service Administrator

-1. Sign in to the [Azure portal](https://portal.azure.com) as an [Owner](built-in-roles.md#owner) of a subscription.

-1. Use the Azure portal or Azure Resource Graph to [list your Service Administrator](#list-classic-administrators).

-1. Review the [sign-in logs](/entra/identity/monitoring-health/concept-sign-ins) for your Service Administrator to assess whether they're an active user.

-### Step 2: Review your current Billing account owners

-The user that is assigned the Service Administrator role might also be the same user that is the administrator for your billing account. You should review your current Billing account owners to ensure they are still accurate.

-1. Use the Azure portal to [get your Billing account owners](../cost-management-billing/manage/understand-mca-roles.md#manage-billing-roles-in-the-azure-portal).

-1. Review your list of Billing account owners. If necessary, [update or add another Billing account owner](../cost-management-billing/manage/understand-mca-roles.md#manage-billing-roles-in-the-azure-portal).

-### Step 3: Replace existing Service Administrator with Owner role

-Your Service Administrator might be a Microsoft account or a Microsoft Entra account. A Microsoft account is a personal account such as Outlook, OneDrive, Xbox LIVE, or Microsoft 365. A Microsoft Entra account is an identity created through Microsoft Entra ID.

-1. If Service Administrator user is a Microsoft account and you want this user to keep the same permissions, [assign the Owner role](role-assignments-portal.yml) to this user at subscription scope without conditions.

-1. If Service Administrator user is a Microsoft Entra account and you want this user to keep the same permissions, [assign the Owner role](role-assignments-portal.yml) to this user at subscription scope without conditions.

-1. If you want to change the Service Administrator user to a different user, [assign the Owner role](role-assignments-portal.yml) to this new user at subscription scope without conditions.

-1. [Remove the Service Administrator](#remove-the-service-administrator).

-Follow these steps to list the number of Service Administrator and Co-Administrators in your subscriptions using Azure Resource Graph.

-## Remove a Co-Administrator

-> [!IMPORTANT]

-> Classic resources and classic administrators will be [retired on August 31, 2024](https://azure.microsoft.com/updates/cloud-services-retirement-announcement/). Starting April 3, 2024, you won't be able to add new Co-Administrators. This date was recently extended. Remove unnecessary Co-Administrators and use Azure RBAC for fine-grained access control.

-Follow these steps to remove a Co-Administrator.

-1. Add a check mark next to the Co-Administrator you want to remove.

-1. Select **Remove**.

-1. In the message box that appears, select **Yes**.

- :::image type="content" source="./media/classic-administrators/remove-coadmin.png" alt-text="Screenshot of message box when removing a Co-Administrator." lightbox="./media/classic-administrators/remove-coadmin.png":::

-## Add a Co-Administrator

-> [!IMPORTANT]

-> Classic resources and classic administrators will be [retired on August 31, 2024](https://azure.microsoft.com/updates/cloud-services-retirement-announcement/). Starting April 3, 2024, you won't be able to add new Co-Administrators. This date was recently extended. Remove unnecessary Co-Administrators and use Azure RBAC for fine-grained access control.

->

-> You only need to add a Co-Administrator if the user needs to manage Azure classic deployments by using [Azure Service Management PowerShell Module](/powershell/azure/servicemanagement/install-azure-ps). If the user only uses the Azure portal to manage the classic resources, you wonΓÇÖt need to add the classic administrator for the user.

- Co-Administrators can only be assigned at the subscription scope.

-1. Select the **Classic administrators** tab.

- :::image type="content" source="./media/shared/classic-administrators.png" alt-text="Screenshot of Access control (IAM) page with Classic administrators tab selected." lightbox="./media/shared/classic-administrators.png":::

-1. Select **Add** > **Add co-administrator** to open the Add co-administrators pane.

- If the **Add co-administrator** option is disabled, you don't have permissions.

-1. Select the user that you want to add and select **Add**.

- :::image type="content" source="./media/classic-administrators/add-coadmin.png" alt-text="Screenshot of Add co-administrator pane to add a Co-Administrator." lightbox="./media/classic-administrators/add-coadmin.png":::

-## Add a guest user as a Co-Administrator

-To add a guest user as a Co-Administrator, follow the same steps as in the previous [Add a Co-Administrator](#add-a-co-administrator) section. The guest user must meet the following criteria:

-For more information, about how to add a guest user to your directory, see [Add Microsoft Entra B2B collaboration users in the Azure portal](../active-directory/external-identities/add-users-administrator.md).

-Before you remove a guest user from your directory, you should first remove any role assignments for that guest user. For more information, see [Remove an external user from your directory](./role-assignments-external-users.md#remove-an-external-user-from-your-directory).

-### Differences for guest users

-Guest users that have been assigned the Co-Administrator role might see some differences as compared to member users with the Co-Administrator role. Consider the following scenario:

-You would expect that user B could manage everything. The reason for this difference is that the Microsoft account is added to the subscription as a guest user instead of a member user. Guest users have different default permissions in Microsoft Entra ID as compared to member users. For example, member users can read other users in Microsoft Entra ID and guest users cannot. Member users can register new service principals in Microsoft Entra ID and guest users cannot.

-If a guest user needs to be able to perform these tasks, a possible solution is to assign the specific Microsoft Entra roles the guest user needs. For example, in the previous scenario, you could assign the [Directory Readers](../active-directory/roles/permissions-reference.md#directory-readers) role to read other users and assign the [Application Developer](../active-directory/roles/permissions-reference.md#application-developer) role to be able to create service principals. For more information about member and guest users and their permissions, see [What are the default user permissions in Microsoft Entra ID?](../active-directory/fundamentals/users-default-permissions.md). For more information about granting access for guest users, see [Assign Azure roles to external users using the Azure portal](role-assignments-external-users.md).

-Note that the [Azure built-in roles](../role-based-access-control/built-in-roles.md) are different than the [Microsoft Entra roles](../active-directory/roles/permissions-reference.md). The built-in roles don't grant any access to Microsoft Entra ID. For more information, see [Understand the different roles](../role-based-access-control/rbac-and-directory-admin-roles.md).

-For information that compares member users and guest users, see [What are the default user permissions in Microsoft Entra ID?](../active-directory/fundamentals/users-default-permissions.md).

-## Change the Service Administrator

-Only the Account Administrator can change the Service Administrator for a subscription. By default, when you sign up for an Azure subscription, the Service Administrator is the same as the Account Administrator.

-The user with the Account Administrator role can access the Azure portal and manage billing, but they can't cancel subscriptions. The user with the Service Administrator role has full access to the Azure portal and they can cancel subscriptions. The Account Administrator can make themself the Service Administrator.

-Follow these steps to change the Service Administrator in the Azure portal.

-1. Sign in to the [Azure portal](https://portal.azure.com) as the Account Administrator.

-1. Open **Cost Management + Billing** and select a subscription.

-1. In the left navigation, select **Properties**.

-1. Select **Change service admin**.

- :::image type="content" source="./media/classic-administrators/service-admin.png" alt-text="Screenshot of subscription properties page that shows option to change Service Administrator." lightbox="./media/classic-administrators/service-admin.png":::

-1. In the **Edit service admin** page, enter the email address for the new Service Administrator.

- :::image type="content" source="./media/classic-administrators/service-admin-edit.png" alt-text="Screenshot of Edit service admin pane to change Service Administrator." lightbox="./media/classic-administrators/service-admin-edit.png":::

-1. Select **OK** to save the change.

-## Remove the Service Administrator

-To remove the Service Administrator, you must have a user who is assigned the [Owner](built-in-roles.md#owner) role at subscription scope without conditions to avoid orphaning the subscription. A subscription Owner has the same access as the Service Administrator.

-1. Select **Remove**.

-If the Service Administrator user is not in the directory, you might get the following error when you try to remove the Service Administrator:

-`Call GSM to delete service admin on subscription <subscriptionId> failed. Exception: Cannot delete user <principalId> since they are not the service administrator. Please retry with the right service administrator user PUID.`

-

-If the Service Administrator user is not in the directory, try to change the Service Administrator to an existing user and then try to remove the Service Administrator.
