I did my 2.1.16 to 2.3.1 update last week and it went smooth. I was
expecting the worse considering the reports of mailbox corruption have
read. When moving files over I did the following:
1) Used rsync to get the files to the new system then
set perms in /var/spool/imap as needed.
2) Moved sieve, quota and seen dbs over, also set perms as needed
3) Only moved the mailboxes.db file and let cyrus recreate anything else
4) After first startup, before letting users login, I did the following:
a) run quota -f to check/fix all quotas
b) loop through all accts with a perl script
to login, read 3 headers from inbox, then log out.
5) Send email to all accts with update information.
6) Allowed for normal account logins.
The whole process went very smooth and I never saw an issue with mailbox
corruption in the logs while doing test logins or sending the email
notification that the update was complete. I received no reports of
missing mail or problems with seen flags.
Maybe for me I was lucky because I skipped 2.2.x completely :)
