That's certainly how we always do it here.  We pause the new email feed at
the MTAs (so that it will just queue), firewall off any user access, run a
full backup, do the upgrade, trigger a full reconstruct and quota rebuild,
and test everything before we restore service.

Better the planned downtime, than surprise breakages.
