IMHO: move all dovecot* files the migration script generates and the 
"subscriptions" file into the control directories, some INBOX-related 
files probably go to <control base>/.INBOX, dovecot-keywords and 
dovecot-uidlist - maybe more. The migration scripts I saw til today never 
create any indexes, so the assumption should be fine. And test it with one 
account, move some messages around, add some subscriptions and ACLs, ...
