Hi. I'm preparing for migrating about 30k account from Netscape Messaging Server to Cyrus (yeah... cyrus rules, NMS sucks ;-) ) And now i want to find out the best solutions for this. NMS has very similar structure of mailboxes 1. Imap Copy 2. Tar ; untar mailbox and reconstruct, 3. Get mails from old mailbox and send directly to deliver process or to lmtpd. What is the best idea and the fastest. There are about 50Gigs of data.
