Hi,

I'm looking for advice.

I'm planning an upgrade shortly from 7.4.3 on Mac 10.5.8 (on an old XServe) to 8.3 on a new Mac Mini running 10.9 (with the mail store on an external RAID).

Question is this: The documentation says to move from one server to another, both need to be the same version. However, 8.3 will not install on 10.5.8, and I'd like to have a clean install (not an upgrade) of 8.3 on the new server.

One idea is to upgrade the OS on the old server to 10.6.8, then upgrade the mail server, then do the backup/restore method to move the mailboxes to the new server. Has anyone upgraded the OS on a mail server and did it cause any problems? I don't care much about performance as I'm only upgrading to get the data off of it; it'll be mothballed when I'm done.

OR

Would it be better to install 7.4.3 on the new machine, move the mail, then upgrade it to 8.3. Does anyone have any actual knowledge of issues with upgrading vs clean-installing, other than it "feels" better to do the latter from an Admin's point of view?

Thanks in advance for any thoughts/tips.

Jeff

I would upgrade the XServe's OS, then Kerio, then use rsync to migrate the data and install the same version of Kerio on the new server.
