I was checking out the following page on the wiki:
http://wiki.qmailtoaster.com/index.php/Replacing_Courier_IMAP_with_Dovecot_IMAP
The 4th section down ("Convert the mailboxes"):
This is the part you really should test. The success or failure of this
part will determine how transparent your migration is to your users.
You'll not likely loose any mail (you have backups, right??), but your
users might end up having to re-subscribe to folders and/or re-download
email headers, depending on the client software they use.
First we'll get the conversion script:
# cd /usr/local/sbin
# wgethttp://www.dovecot.org/tools/courier-dovecot-migrate.pl
...
# chmod 0700 courier-dovecot-migrate.pl
# cd ~vpopmail/domains
This command will do a "dry run" to make sure things will work correctly...
# /usr/local/sbin/courier-dovecot-migrate.pl --recursive
You should see your user accounts scroll by and say something like
"UIDLIST not found" but nothing else. At the end of the script you
should have 0 ERRORS.
This command actually does the conversion.
# /usr/local/sbin/courier-dovecot-migrate.pl --recursive --convert
If everything went well, you can proceed. If not, you might want to post
a message to the qmail-toaster list to get some help.
This is the script I was referring to. Is it necessary to do this?
Sometime in the not-so-distant future I'd like to set this new server up
to replicate to another offsite QMT box...I've purchased and viewed
Jake's Replicated QMT videos and was planning on doing something
similar, however last time I recompiled vpopmail I noticed the
"--enable-mysql-replication" option and wasn't sure if that would be
something I would need to compile in to do the replication or not. The
video doesn't mention it, and the documentation briefly rattles off
something about read-only replication from a master server. Any chance
anyone could provide me with a bit more in-depth explanation?
Last but not least (at least for today...), what about QControl? Is this
something I should look at purchasing? The screenshots make it look
kinda nifty, but I was hoping to someone else' input.
Thanks!

Eric,
I looked over the Dovecot article on the wiki...seems straightforward
enough, but the one thing I was wondering - should I proceed with
migrating everything as I am now and then when I have the first batch
everything moved over, then install Dovecot and run that migration
script?
No, I would install and use dovecot from the get-go, before doing any
migration. The filesystem structure for maildirs is the same.
I'm guessing that I'll need to run that script any time that
maildirs are copied from the old server, correct?
Which script would that be?
You can drop emails from wherever (your script) into the Maildir/new
directory anytime/anyway, and dovecot should figure out how to handle
it. I think. Imap-wise anyhow. I don't think pop would be a problem
either, although I haven't exactly done that, to be honest.
