i have a filer on 7.2.4 with a very large volume size of 12164g. i need to do some loop reorginzation and want to snapmirror it off to a newer filer running 7.3 and then delete it to free up space for some other volume migrations and shelf swaps. when all is said and done i want to put this volume back. so the question is will i be able to snapmirror it back from 7.3 to 7.2.x?
