I rsync'ed from one mailserver to another and excluded the courier
related files. Then I crawled each user's imap folders on both systems
with a perlscript and wrote out the results to two files.

As you suggest various logs/indexes were created by dovecot and all my
accounts were the same. Baring a few deliveries. You will loose folder
subscription information remember and I know nothing about shared
folder stuff.

Btw, the difference between courier and dovecot is insane the dovecot
machine I am using is not a 3rd of the courier machine and the speed
is quite impressive. I hope to see an additional advantage to using
dovcot's lda deliver to prep these indexes as well.
