I've got Zimbra 3.1 running on a 2.1Ghz Celeron with 2G ram with 300 mailboxes/users. They are about 50% web client and the rest are IMAP or POP. It was running very well until i upgraded to 3.1 and it has not been very stable since. frequently the logger process would eat all the CPU cycles. So now I just stop it altogether. Now it will run for almost 3 days at shot (yippie) before one of the processes bombs out and I have to shutdown & restart it.

I've got a shiny new dual Xeon server with 3G ram that I'm dedicating to Zimbra. Can anyone offer any advice as to how to move my users and mailboxes to the new server without bringing over the grief with it?

Thanks in advance.
