I am upgrading a server and I need to migrate all the account on the zimbra server from one to the other. I am currently running zcs-5.0.14_GA_2850.UBUNTU6.20090303170507
and will be upgrading to zcs-5.0.16_GA_2921.UBUNTU8.20090429045342
If it help I can upgrade the older server to 5.0.16_GA first.
What is the easiest way to move all the accounts/data??
