Jack - What's going on? I already have a process in place, and with the exception of the GSSAPI issue, worked quite well. It also didn't involve any down time in the process, which, your way will result in a 6-8 hour outage... The issue with the quota has been already addressed, and will be read from the old server and set during the account creation process. The only thing that will need to be copied by hand is the sieve scripts (And I am working on automating that also... ) If there are any professional reasons why you dislike my process, please raise those concerns with me and I will address them. Otherwise, let's set a date for the migration and I will take it from there... >>> Jack Neely 04/20/09 5:59 PM >>> Folks, Thought I would write down our current rumblings of a plan and status: Right now, uni50map is a mirror of uni23map on April 7th and should be working as a "normal" imap server. We need to toss some more testing at it. We have decided not to use the EMC snapshots to move the data to the new hardware. 1) It creates a lot of IO on the EMC arrays which we've been conserned with before. 2) The IO load means that we would not be able to migrate servers as fast as we'd like. So, unless we have some compelling reasons to revisit (Patrick, please feel free) we'd just like to do a cpio/rsync over an SSH tunnel. Tim is writing a bit of perl magic to handle mupliple cpio streams to make the data flow to the new server as quick as possible. So a production upgrade now looks like this: * Deffer mail * Remount /imap read only on the affected imap server. mount /imap -o remount,ro * Move data to new server * sudo -u cyrus /local/cyrus/sbin/reconstruct -rf 'user.*' * sudo -u cyrus /local/cyrus/sbin/quota -f * Update hesiod * Un-deffer mail How long will this take. I'm questimating 3 to 4 hours to move data and 3 to 4 hours to reconstruct/quota fix. I've no clue how long the hesiod/dns update will take. ;-) Jack -- Jack Neely Linux Czar, OIT Campus Linux Services Office of Information Technology, NC State University GPG Fingerprint: 1917 5AC1 E828 9337 7AA4 EA6B 213B 765F 3B6A 5B89
