Vmware Parent CID Mismatch

Good Evening All,

I have a ESX 5 with sbs 2011 in a VM, they filled there datastore and the sbs instance crashed, after releasing some space on the datastore the server would no longer boot, i attempted to create a second instance with the drives attached but wrongly booted there master VM and now it comes up with parent has been modified since the child was created.

The end client only has a backup of the master vmdk file back in october if this master file is restored will the PID match?

Any help appreciated.
