Azure classic subscription administrators

Important

As of August 31, 2024, Azure classic administrator roles (along with Azure classic resources and Azure Service Manager) are retired and no longer supported. If you still have active Co-Administrator or Service Administrator role assignments, convert these role assignments to Azure RBAC immediately.

Microsoft recommends that you manage access to Azure resources using Azure role-based access control (Azure RBAC). If you're still using the classic deployment model, you'll need to migrate your resources from classic deployment to Resource Manager deployment. For more information, see Azure Resource Manager vs. classic deployment.

This article describes the retirement of the Co-Administrator and Service Administrator roles and how to convert these role assignments.

Frequently asked questions

What happens to classic administrator role assignments after August 31, 2024?

  • Co-Administrator and Service Administrator roles are retired and no longer supported. You should convert these role assignments to Azure RBAC immediately.

How do I know what subscriptions have classic administrators?

  • You can use an Azure Resource Graph query to list subscriptions with Service Administrator or Co-Administrator role assignments. For steps see List classic administrators.

What is the equivalent Azure role I should assign for Co-Administrators?

  • Owner role at subscription scope has the equivalent access. However, Owner is a privileged administrator role and grants full access to manage Azure resources. You should consider a job function role with fewer permissions, reduce the scope, or add a condition.

What is the equivalent Azure role I should assign for Service Administrator?

  • Owner role at subscription scope has the equivalent access.

Why do I need to migrate to Azure RBAC?

  • Azure RBAC offers fine grained access control, compatibility with Microsoft Entra Privileged Identity Management (PIM), and full audit logs support. All future investments will be in Azure RBAC.

What about the Account Administrator role?

  • The Account Administrator is the primary user for your billing account. Account Administrator isn't being deprecated and you don't need to convert this role assignment. Account Administrator and Service Administrator might be the same user. However, you only need to convert the Service Administrator role assignment.

What should I do if I lose access to a subscription?

Co-Administrators retirement

If you still have classic administrators, use the following steps to help you convert Co-Administrator role assignments.

Step 1: Review your current Co-Administrators

  1. Sign in to the Azure portal as an Owner of a subscription.

  2. Use the Azure portal or Azure Resource Graph to list of your Co-Administrators.

  3. Review the sign-in logs 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.

  2. If user was deleted, but their Co-Administrator assignment wasn't removed, remove Co-Administrator.

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

  3. After reviewing activity of user, if user is no longer active, remove Co-Administrator.

Step 3: Convert Co-Administrators to 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 they need.

  2. Determine the scope user needs.

  3. Follow steps to assign a job function role to user.

  4. Remove Co-Administrator.

Step 4: Convert Co-Administrators to Owner role with conditions

Some users might need more access than what a job function role can provide. If you must assign the Owner role, consider adding a condition or using Microsoft Entra Privileged Identity Management (PIM) to constrain the role assignment.

  1. Assign the Owner role with conditions.

    For example, assign the Owner role at subscription scope with conditions. If you have PIM, make the user eligible for Owner role assignment.

  2. Remove Co-Administrator.

Step 5: Convert Co-Administrators to Owner role

If a user must be an administrator for a subscription, assign the Owner role at subscription scope.

Service Administrator retirement

If you still have classic administrators, use the following steps to help you convert the Service Administrator role assignment. Before you 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 as an Owner of a subscription.

  2. Use the Azure portal or Azure Resource Graph to list your Service Administrator.

  3. Review the sign-in logs 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.

  2. Review your list of Billing account owners. If necessary, update or add another Billing account owner.

Step 3: Convert Service Administrator to 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, convert the Service Administrator to Owner role.

  2. If Service Administrator user is a Microsoft Entra account and you want this user to keep the same permissions, convert the Service Administrator to Owner role.

  3. If you want to change the Service Administrator user to a different user, assign the Owner role to this new user at subscription scope without conditions. Then, remove the Service Administrator.
