April 2024

The retirement of Azure classic administrator roles, including Service Administrator and Co-Administrator, is a significant change scheduled for August 31, 20241. This move is part of Microsoft’s ongoing efforts to streamline and modernize its role-based access control (RBAC) across Azure services.

Here are the key points regarding this transition:

Transition to Azure RBAC: Organizations with active classic administrator roles must transition to using Azure RBAC roles by the retirement date.

End of Adding New Roles: Starting from April 3, 2024, it is no longer possible to add new Co-Administrator roles through the Azure portal.

Migration Recommendation: Microsoft advises migrating resources from the classic deployment model to the Resource Manager model to better manage access using Azure RBAC2.

Support and Guidance: For those who need assistance or have a strong dependency on classic administrators, Microsoft has provided resources and support channels, including the possibility to contact them directly via email3.

This update emphasizes the importance of preparing for the retirement by transitioning to the newer RBAC roles to avoid any potential disruptions in service. For more detailed information and guidance on this process, you can refer to the official Azure updates and Microsoft Learn documentation.
