Afai understand this would mean these 3 dirs:

configdirectory: /var/lib/imap
partition-default: /var/spool/imap
sievedir: /var/lib/sieve

sigh ... I don't even *know* if I use berkeley.

# ls /var/lib/imap
annotations.db
db
db.backup2
deliverdb
mailboxes.db
[...]

Is the conversion hard to do?
What do you recommend?
