Hello Olly Thompson,
Greetings! Welcome to Microsoft Q&A Platform.
I understand that you would like to migrate Azure NetApp Files (ANF) to a parent domain while dealing with the limitation of a single Active Directory (AD) connection per region.
Azure NetApp Files provides NFS and SMB volumes. You can use any file-based copy tool to migrate data to the service. For more information about the Azure File Migration Program, see Migrate the critical file data you need to power your applications. Also, see Azure Storage migration tools comparison - Unstructured data. NetApp offers a SaaS-based solution, NetApp Cloud Sync. The solution enables you to replicate NFS or SMB data to Azure NetApp Files NFS exports or SMB shares.
You can create a new AD connection for the parent domain in each region. This will involve setting up a new NetApp account, if necessary, as each NetApp account can have its own AD connection.If modifying the existing AD connection is an option, you can update the AD connection to point to the parent domain. However, be aware that not all configurations are modifiable, and changes can be disruptive refer here for more details- https://learn.microsoft.com/en-us/azure/azure-netapp-files/modify-active-directory-connections,https://learn.microsoft.com/en-us/azure/azure-netapp-files/create-active-directory-connections.
Ensure that the new AD connection in the destination region has access to the necessary DNS servers or AD DS Domain Controllers. Before fully decommissioning the child domain, thoroughly test the new setup to ensure that all services and data are accessible and functioning correctly per the requirements here - https://learn.microsoft.com/en-us/azure/azure-netapp-files/cross-region-replication-requirements-considerations.
