VMware HCX
On RAV/Bulk migration, It will run a checklist for different processes and services running in the VM. One of the steps is to enable replication for the VM. If it detects that the replication is already enabled, it will fail with that error to avoid any impact in case other applications in the VM are working with replication at that moment.
To remediate this issue you need to disable the pre-existing replication configuration of a VM or cancel/stop the replication process of the VM.
