Hi Sean,
Please reply to the list otherwise the list my stay full of questions only.
I have copied folders from one machine to another without shutting down
the server.
I dont think that you need to rsync the whole repository if you want
only some accounts moved.

I dont know know much about your setup, but my Cyrus servers run with
postfix+LDAP so I can do mailrouting to more than one box at a time.
Example:
I have a record for a user called atif
dn: uid=atif, blah blah
mailacceptinggeneralid: [EMAIL PROTECTED]
maildrop: [EMAIL PROTECTED]
If I want to move this user to a box called cyrus2 I will add a second
maildrop to its record
dn: uid=atif, blah blah
mailacceptinggeneralid: [EMAIL PROTECTED]
maildrop: [EMAIL PROTECTED]
maildrop: [EMAIL PROTECTED]
now I can copy its files to another box and then reconstruct the db.
Any mails that arrive in the mean time will go to both cyrus servers, so
most probably the mails will not be lost.

What do you mean by stand-by cyrus server? Is this like a backup box
that takes over if one fails?
If yes, then after you have copied the cyrus rep and the databases make
sure that mail for each user is routed to both boxes.
cheers
