Stefan,
I haven't had problems with upgrading, but I didn't "wait" this long.
Eg. I didn't migrate from 2.1 to 2.4 directly.
I would suggest you check on the cyrus-imap mailing list (see bottom of
email) for tips. Installing it is simple, but there are a few changes with
some of the files.
A safer method would be running the 2 versions in parallel and using
imapsync or something similar to copy the email over to the new version.
