Snapshot error in VM server which is moved from PROD to DR site

Hi All,

In my environment most of servers are VMs . We are on Netbackup 7.6.1.2 and Windows 2008 R2 master.We are backing up only production VM (Most of them are Window ) and only prodution Vcenter server has been added in Netbackup->credential.There is also DR Vcenter server which is not added  in Netbackup.

A VM server ( Windows) recently got migrated from PROD to DR after that backup started failing (Policy type VMWare ; Media server is our backup server ). I am looking for a solution to which helps me to take backup this server ( like backing up replicated data )

Regards
