Cyrus 2.1.11 on BSDi 4.3.1

[Echo Online Development Team]

Does anyone have any experience doing this migration (From Berkeley to 
Skiplist)?  We have aprox. 12,000 active mailboxes - what potential 
issues could we run into?  What impact will this have on the 
performance of our IMAP server?

Thanks in advance,

M. Gamble
