If you have double diskspace:
Just use "dsync mirror" in the background to prepare the change. After that
it's just a short downtime to migrate incremental the last changes, or it's
just a question of a short login-script.
if [ -d ~/Maildir ] ; then
dsync mirror voodoo-magic
rm -R ~/Maildr

I wonder about that problem too. Even the last-last-last-quick sync would be
so much IO, that I can't handle it in realtime in the morning at 9 a.m.
Looks like a nightly downtime for the last incremental run.
It would be MUCH easier if Dovecot could read maildir: or mdbox: from LDAP
attributes. In this case the whole migration process could be split up into
groups. Unfortunately we have shared folders and I don't know a way to read
the *remote* mailbox-format from LDAP... So having users with maildir and
mdbox mixed up will break their shared folders...
