Migrating Zimbra from 4.5.10 to 5.0.10
I'm a ZCS version 4.5.10 user, so, it's time to upgrade to a new version - 6.0.6. But I have some a doubt:
1-) I need to export user accounts, so, I've read that it's possible by using the following command:
/opt/zimbra/bin/zmmailbox -z -m email@example.com getRestURL “//?fmt=tgz” > /tmp/account.tgz
But I've checked that the command it's only available on 5.x versions.
So, do I need migrating from 4.5.10 to 5.x, exporting accounts and finally upgrading from 5.x to 6.0.6? If it's correct, what are the steps to do it?
Thanks a lot.
