I did the same.  I'm sure you'll be pleased by the results.  I assume
you are using 1.0 and not 0.99 versions?

There is nothing wrong with staying with mbox.  There may be reasons it
is best or better to do so (then again, there could be reasons to go
to maildir instead -- it all depends on your needs and setup).

There are few pages about the migration because there is so little to
do for it.

Did you set up your UID format properly in dovecot.conf?  It should be:

pop3_uidl_format = %08Xv%08Xu

Other than that, it should pretty much work from my experience...

Not sure I helped any, but you're welcome in any case.
