dovecot - Mar 2009 - Upgrade from 1.0 to 1.1, plus migration from Maildir to dbox

Ok - I gave up on trying to get CIFS to work - there's obviously stuff
going on I don't understand.  So - instead of trying to get a virtual
server to work, I next tried a chroot.  That worked...but imapsync
error'ed out trying to handle one of my large mailboxes.

I was trying to setup a "new" server, migrate all my mail over, verify
everything worked - maybe even leave the virtual server operating for a
while.  But the fates are consipiring against me.  So - time to make the
leap.  I want to upgrade a live version 1.0 server to version 1.1 (from
Ubuntu repositories, using version 1.0.10 to 1.1.4).

What special steps do I need to take to have this go smoothly?  At least
I have some semi-tested configs for 1.1 that I can use.  Do I just stop
the server, upgrade, upgrade the configs, start - and pray?  Or is there
another step?

Also, my legacy installation was using maildir - I'd like to try
shifting to dbox.  Do I just need to change the prefix on mail_location
and the conversion will magically happen?

I did this recently on a Solaris install which was originally running 
0.99.x, then 1.0.x and now 1.1 :)

Nope.. that's all there is to it, unless the Upgrade notes on the dovecot 
wiki say otherwise.  See http://wiki.dovecot.org/Upgrading/1.1

Hell no.  Converting between mail store formats is not done automagically, 
and should never be seen as a 'trivial' action.

http://wiki.dovecot.org/Migration/MailFormat should be a good starting point.

Why? Current version is 1.1.13, and 1.2 is close to RC...

Personally, unless you have an uncommon setup, I'd go straight to 1.2b4...
