Just so long as nothing mentions berkeley or is left to defaults of
berkeley in the imapd.conf, it's probably fine.  Actually, now that
you've removed all the old cruft, it will probably keep working fine
even if you do leave things as berkeley.

Ahh.  Excellent.

No, you won't need to run it again.  The reconstructs have run once already,
so the indexes are already upgraded.

It's a good idea to run it so that it upgrades all the indexes one at a time -
otherwise they will be upgraded the first time that each mailbox gets opened.
(in 2.4 at least - in 2.5 and later, you have to manually upgrade the indexes
to avoid the IO storm of having it all happen at once)

It's always nice when things just work!
