Replicated murder question

[Martin Wendel]

I'm trying to set up a replicated murder (Cyrus 2.3). I've got a  
shared storage
using IBM SAN-FS, two IMAP-servers (AIX) and a mupdate master. The  
plan is to
use two load-balancers with this solution, connecting to the IMAP- 
servers.
Since I'm new to murder I wish to get some confirmation that I'm on  
the right
track. It is a test environment but is planned to go into production  
within a
month or so. I'll attach config files below.

Mupdate seems to work, adding mailboxes on one of the IMAP-server  
propagates
to mailboxes.db on the master and the other IMAP-server. Running  
ctl_mboxlist -m
on one of the IMAP-servers removes all mailboxes:

# su mail -c ctl_mboxlist -mw
Remove Local Mailbox: user.test1
Remove Local Mailbox: user.test10
Remove Local Mailbox: user.test11
Remove Local Mailbox: user.test12
Remove Local Mailbox: user.test13
Remove Local Mailbox: user.test14
Remove Local Mailbox: user.test15
Remove Local Mailbox: user.test16
Remove Local Mailbox: user.test17
Remove Local Mailbox: user.test18
Remove Local Mailbox: user.test19
Remove Local Mailbox: user.test2
...

So I figurered, remove this from the START in cyrus.conf. After that  
it seems to
work, but I'm unsure if this is the right way.

We've got a single cyrus IMAP-host in production today, and plan to  
migrate all
mailboxes to the new murder. It is about 1TB spool in a single  
filesystem so it
is not a good way to just sync the filesystem. Mailboxes must be  
migrated using
IMAP or murder mechanism. Would it be a working approach to include  
the production
server in the murder and migrate using 'rename'? sync_server seems  
not to be
working on the test machines, however. What is the best way to do  
this, imapsync?
