cyradm +reconstruct all mailboxes (2.3.xx)

[Eero Hänninen]

Hi,

That's because You don't have copied over from old machine seen state 
files. They are located somewhere 
/var/imap/user/$user_letter/$username.seen or so. But if you copy them 
now, then you restore old mails states, but mails what arrived after 
migrating process will be marked again unread - so users will be 
confused again. Anyway, if you still plan copy seen state files over, 
then you must run reconstruct again.

P.S. This manual user migration is very complicated process and 
mistakes will happen very easy, so I strongly recommended, that you test 
with 1 or 2 mailboxes before such kind migration and make sure that 
after test migration mailboxes work correctly on new system.
Its better use imapsync or such tool, to sync user mailboxes and mail 
states..

Rgrds,
Eero
