Reconfigure replication fails after re-protect when changing the target datastore for a vmdk

After performing re-protect operation, reconfigure replication that involves disk moves might fail.

Problem

After performing reprotect operation, reconfigure replication that involves disk moves, for example moving the disk to another datastore or path, fails with the following error:

Unable to complete the reconfiguration task at remote site for replication group 'hbr-vm' (managed object ID: 'GID-xxxx'): task 'HTID-xxxx'. 
Details: 'A runtime error occurred in the vSphere Replication Management Server. 
Exception details: 'VR Server error: 'Virtual Machine exists at the target datastore path'.

Cause

The problem can occur when there is disk with the same name at the target location.

Solution

You must rename or move the vmx of the original virtual machine at the target location.
