Best method for migrating mailboxes between versions
I have a zimbra 5.04 (OS) system that I'm about to replace with a 6.0.6 (OS) install. I've redone the underlying OS to bring it up to date as well.
There are only 2 mailboxes that I care about enough to move.
I've used the items.zip, but can see that it can't track the received data and other useful items.
I can't use the
/opt/zimbra/bin/zmmailbox -z -m firstname.lastname@example.org getRestURL “//?fmt=tgz” > /tmp/account.tgz
As my live zimbra version is too old.
What is going to be the best way to retain that detail?
Should I use a POP3/IMAP setup to do this? Is there an alternative?
Am I going to be better off upgrading the old system to 5.10 or later to get that function?
