Reversing snapmirror between C Mode and 7 Mode

I have a volume level snapmirror which source is on 7 Mode and DR is C-Mode (We are in the middle of product upgrade). In this scenario, Just wonder, can I perform snapmirror reversal to change replication from C Mode to 7 Mode? If so, how can I do it?

Source (7 Mode) is FAS6080 and running 8.1.3 and DR (C Mode) is FAS8080 and running 8.3.1.

Thank you!
