I moved a few thousand mailboxes in a similar fashion (summer of 2007) and
encountered no problems. New message deliveries were nicely "frozen" by
Cyrus while the target Inbox was being renamed/moved.
Question : would it, stabilitywise, make a difference if the mail data and metadata
are split, allocating the metadata partitions on SAN-based LUNs and storing messages
in NAS (NFS) space ?
In other words : are the Cyrus-over-NFS inconveniences confined to the cyrus.* files ?
NAS space can, typically, be "grown" more easily than SAN space.
This could be an advantage to older server OSes en filesystems...
