Migrating from Open Source to Network Edition?

[bhwong]

We have a open source edition and we want to upgrade to network edition. Can we perform an upgrade on our open source server or do we have to install a new network edition server instead?

If we have to install a new network edition instead of upgrading. How do we migrate all the accounts over to the new server since open source do not have a backup and restore function?

btw, as network edition is charge base on number of accounts, for outgoing staffs leaving our organization, is there a way to archive their account? Will Zimbra still charge us for these archived or inactive accounts?

What about Zimbra Archiving and Discovery module? Do we need an active account for ZAD to works? Or can we archive them into ZAD and remove these inactive accounts from Zimbra.

Upgrade from OSE to NE is easy; no reinstall required. You get an NE license file from Zimbra, put it on the server, let Zimbra know its there and you are pretty much done.

For outgoing staff, you can archive their mailbox to an Outlook PST file and then destroy their mailbox. Then if you need to look at their mailbox later, you can just import it into a new Outlook profile and not even bother with Zimbra.

ZAD consumes a second license for each mailbox protected, because ZAD creates a second, totally separate untouchable-by-humans mailbox for each mailbox protected with ZAD.

Don't think of ZAD as backup; think of it as a legal archiving/discovery service (which is what it was designed for in the first instance).

Hope that helps,

Don't you have to do an 'upgrade' with the NE installer? I've never done an OSS -> NE migration, but I have done several NE -> OSS migrations.. I would imagine they'd be the same.

You do run the NE installer (same ZCS version as the installed OSE) yes, but we think of "upgrades" as going from one version number to a more recent version number and "reinstall" as wiping old data to install Zimbra fresh.

Semantics can be fun, eh?

All the best,

Ok, so after we received the license, all we need to do is to stop the OSS version and reinstall the NE over it and all accounts and settings will be carry over without anything missing right?

Yes, but dont stop the server, let the installer do that; it likes to check some things before the install and the server needs to be runnning for that.

It's essentially the same process as a normal upgrade, you just install with the NE installer on the same version as you currently are running. And yes, it will carry over user data, settings, etc.
