I've been given the task of migrating from our old zimbra mail server (Release 6.0.6_GA_2324.RHEL5_64_20100406150533 CentOS5_64 FOSS edition.) to a new server (7.1.3_GA_3346.RHEL6_64.20110928134428).

Is the migration as easy as copying over the /opt/zimbra folder to the new /opt directory then installing zimbra on the new server? I'm running across problems and it doesn't seem as easy as that. Can anyone please respond and point me in the right direction? Thanks in advance.
