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 ?


Rationale : 
  NAS space can, typically, be "grown" more easily than SAN space.
  This could be an advantage to older server OSes en filesystems...
