mailbox move between partitions

["Eero Hänninen"]

Hi!

I have large mail system with multiple mail partitions without murder setup.
And time to time there is need to move user mailboxes between partitions.
In cyrus 2.2 it will work fine, but in cyrus 2.4 it says that mailbox
already exists. So my question, have I do something wrong or is there
things changed or will this sound like a bug ?

Tested on two different servers:

1.server
Linux Debian Lenny 5 (64-bit)
cyrus-imapd-2.4.6 (pulled via git: branch 'debian-sid' of
git://git.debian.org/git/pkg-cyrus-imapd/pkg-cyrus-imapd-2.4)

partition-04: /mnt/mailspool04/mh2_mailspool04

And seems like nothing useful appears to log..

Thanks!
