> First of all, you mean you have only one mbox file per user?
The old server is a POP3 only. It does not support IMAP. On the old server each
user has one Inbox in eg: /var/spool/mail/user <- 'user' being the the mbox
file
I moved the mbox file user into /home/trans, created /oldhome/user and ran your
command as best I understood it.
The results are below.
[root@srv1 ~]# ls -lR /oldhome
/oldhome:
total 4
drwxrwxrwx 2 user root 4096 Sep 12 11:06 user
/oldhome/user:
total 0
[root@srv1 ~]# ls -lR /home/trans
/home/trans:
total 29992
-rwxrwxrwx 1 root root 30709562 Sep 12 09:53 user
[root@srv1 ~]#
[root@srv1 ~]# dsync -u user mirror mbox:/oldhome/user:INBOX=/home/trans/%u
dsync(root): Fatal: Mail locations must use the same virtual mailbox hierarchy
separator (specify separator for the default namespace)
[root@srv1 ~]#
[root@srv1 ~]# dsync -u user mirror mbox:/oldhome/user:INBOX=/home/trans/user

First of all, you mean you have only one mbox file per user? If the users used
IMAP protocol, you should have more than one mbox. The idea is that you first
configure Dovecot to point to maildirs, and then use for example:
dsync -u user mirror mbox:/oldhome/user:INBOX=/home/trans/%u
Where /oldhome/user/ would have the non-INBOX files.

You don't have to worry about indexes.

dsync should preserve all the UIDs and POP3 UIDLs, assuming you have the same
pop3_uidl_format setting.
