So, we're about 5 hours away from a major store to store zmmboxmove job.

It occurred to us today, that we have no idea how we might back out if an account doesnt work on the destination. zmmboxmove doesnt "purge" the account on the source, unless you run zmpurgeoldmbox. So this makes me thing its at least possible to back out, and go back to the old mailbox data if necessary. The question is.. How?

I've tried switching zimbramailhost for the account back to the source, and that doesnt seem to work, how else might i accomplish this?
