Currently we are using Zimbra OpenSource 7.2.x. I've installed the same Network version for testing. I want to provision it, but not fully migrate yet. According to the documentation, "Network Edition Moving from Open Source to Network Edition ZCS" (Network Edition Moving from Open Source to Network Edition ZCS - Zimbra :: Wiki), I'd basically be migrating to a new server. I'm just wondering if it might be better in my situation to skip the final section, "Moving the email store & index" and do that when and if we migrate over to the new server.
