both should work
I created a replication session for a VDM from source_VNX to destination_VNX. While i was trying to create replication session for the file system, on the destination side, I placed it on the physical datamover instead of the vdm.  To rectify this I see two option  Option 1 :- One is to delete the current session and create a new session and place the file system correct in the vdm  ( Cleaner option)  Option 2 :-  Remount the file system from physical data mover to the vdm.  ( Will this work ? Is there anything else that needs to be done like to full sync after mounting file system ?
