Azure migration from one tenant to another tenant

CINAR Tarik Greetings & Welcome to Microsoft Q&A forum!

I want to migrate a subscription from tenant A to tenant B, but on this subscription, I have the Azure OpenAI resource. Will the migration impact Azure OpenAI ?

Transferring an Azure subscription to a different Microsoft Entra directory is a complex process that must be carefully planned and executed. Many Azure services require security principals (identities) to operate normally or even manage other Azure resources.

As per my understanding transferring a subscription to a different tenant can impact your Azure OpenAI resource. When a subscription is moved to a different tenant, all principal IDs change, role assignments are deleted from Azure resource, and system assigned managed identities are dropped.

To ensure that your Azure OpenAI resource continues to function properly after the migration, you will need to take steps to recover it. You can follow the instructions from the documentation Business Continuity and Disaster Recovery (BCDR) considerations with Azure OpenAI Service to implement Business Continuity and Disaster Recovery (BCDR) for your Azure OpenAI applications.

Please check Understand the impact of transferring a subscription for more details of the impacts of transferring to a different subscription.
