VMware HCX
There was a third-party backup job running on the VM, hence failing to disable the replication service on the source VM.
Perform a Force Cleanup of the migration in the HCX UI and retry the migration.
If the error persists after a force cleanup, article to manually disable vSphere Replication.
Once replication is disabled, you can proceed with the migration again. If the above steps does not resolve the issue, please open a support case with Broadcom Support.
