The following migrations are not recommended, but can be performed with some limitations.

• Exchange should be migrated by installing newer versions of Exchange Server in parallel with existing production environments, then move user mailboxes from the old system to the new one.
• Domain Controllers should be migrated by preparing a new domain controller, and then migrating the Flexible Single Master Operations (FSMO) roles.
• Move migrates database VMs similar to any other VMs; however, the migration happens at the VM level, not the application level. Move will not perform any application-level changes, disk layout updates, or best practices on the migrated VM. 

  Nutanix recommends you to apply Nutanix best practices to create additional vDisks and rebalance data across those disks to take advantage of the parallel nature of Nutanix distributed storage. For Nutanix best practices, refer to Solutions Documentation.

  When migrating third-party appliance VMs, Nutanix recommends the following:

  • Checking with the vendor and Nutanix Support regarding AHV support for the third-party appliance.
  • Following the vendor-recommended best practices for running in AHV environment.
