Azure migrate | not able to start the replication of Physical servers.

Hi All,

We are experiencing trouble initiating the replication of physical servers due to a compatibility matrix issue; physical servers with BIOS support 2TB of OS disks, but the servers' OS disks are 2233GB; is there any way to duplicate the image of the OS disks and deploy in Azure?

Thanks

Veera.

    Hello @Veera Thank you for posting your question on the Microsoft Q&A platform. Happy to help!

    Based on the information you provided, I understand that you are experiencing issue while trying to migrate your on-premises physical machine to Azure due to disk limitations.

    Based on the Azure Migrate support matrix, the maximum OS disk size for a generation 1 VM is 2 TB. Unfortunately, there is no way to duplicate the image of the OS disks and deploy them in Azure. Support matrix doc link - https://learn.microsoft.com/en-us/azure/migrate/migrate-support-matrix-physical-migration#physical-server-requirements

    However, you may be able to work around this issue by reducing the size of the OS disk on the physical server to 2 TB or less before initiating the replication. Alternatively, you could consider migrating the server to a generation 2 VM, which supports up to 4 TB OS disks.

    If neither of these options is feasible, you may need to consider other migration methods or consult with a Microsoft support professional for further assistance.

    Hope this helps!
