2012 R2 Move Replicated VM to new storage - old location still has VHD?

I have this scenario:

Server 1 (Primary Hyper-V)
Drive 1 (Current VHD storage)
Drive 2 (New VHD storage)

Server 2 (Replica Hyper-V)

I am moving a couple of VM from drive 1 to 2 using live storage migration. These VM have active replication to Server 2. The move seemed to go fine and replication resumed properly once the move was finished. The strange thing is the primary VHD seem to still be on Drive 1. I thought that the final step of the live storage migration would be to delete the old VHD? Once I verify the VM are using Drive 2 I assume I can just delete the files on Drive 1 right?
