This issue occurs due to restrictions on the minimum allowed hardware version for source virtual machines in the Host Based Replication technology.

This is an expected behaviour when the hardware version of the source virtual machine is version 6 or lower.

To resolve this issue, update the hardware version of the source virtual machine to version 7 or higher.
