Hi Simon,

looks like you did not import a dump of mailboxes database on 
destination. And also did not copy user,quota,sieve folders.

 From my memory:

a) On $origin server:
- dump mailboxes.db to text file
# ctl_mboxlist -d > /tmp/foo

b) on $destination server:
- copy from _$origin with permissions(assuming default paths on rhel7/8):
/var/spool/imap/*
/var/lib/imap/sieve/*
/var/lib/imap/user/*
/var/lib/imap/quota/*
your /tmp/foo mailboxes dump file

- import mailboxes
# ctl_mboxlist -u < /tmp/foo
(check uid/gid of /var/lib/imap/mailboxes.db after import)

- run reconstruct
# reconstruct -r -V max user/whatever

Note that if you have user names with dots (e.g. foo.bar), you will have 
to rename sieve folders from foo^bar to foo.bar

Hope it helps. I could have forgotten something, though.

Javier.
