What does cyradm say:
lm user.<user>*
( pick a user with folders ). 
Are users folders listed?

acl is about what user X is allowed to do with mailbox Y, subscription
is about 
whether he wants to see it.

imapsync couldn't do migration the way i wanted ( keeping uidl ),
therefore
i didn't used it and i am not familiar with it. It's possible it did
good job 
creating folders/mailboxes though.

Yes, you can. Otherwise subscriptions wouldn't make any sense. 
You should be able to see all your folders, subscribed or not ( maybe 
you just need to change view filter in your MUA subscription manager ).

Anyway - migrating subscriptions is another thing sucessful migration
should take care of.

To avoid numerous complaints about missing folders it's safer to 
subscribe user to all his folders than waiting for all the users 
subscribing themselves back to the ones they want within next months :) 


If you're in a middle of a big after migration f*ckup i suggest you to 
pick flatfile format for your subscriptions
( subscription_db: flat option in imapd.conf ) 
and regenerate subscription files for all the users

Example:

user: test
subscription file: /var/imap/user/t/test.sub
subscription file content:
user.test.folder1
user.test.folder2
user.test.list
user.test.list.cyrus
user.test.list.fbsd-ports
user.test.monitoring
user.test.monitoring.nagios
user.test.monitoring.netcool

NOTE:
don't forget extra tab (\t) before the end of the each line. 
That's one of the things you usually discover in the middle of the
night during migration :)
