Make sure that the same partitions are configured on master and replica

Cyrus replication is not integrated with the murder setup.
A replica MUST NOT have a mupdate server configured.

Have you tried calling sync_client on the master with the "-u" option
(See sync_client manpage for details https://linux.die.net/man/8/sync_client)
This should sync all mailboxes, of the user and move the mailboxes to the
correct partition.

If this fails check for errors in the logs.

An other option would be to move the mailboxes to the correct partition with
cyradm using the renamemailbox command

   renamemailbox oldname newname [partition]
