Updating Mac OS X 10.4-based ZCS 5.0.13 server to 10.5 Leopard

[Mark Daniel]

Heya all,
I have a Mac OS X 10.4.11 Server box hosting ZCS 5.0.13 OSE. I just noticed that 10.4 support will be ending with 6.0, so I'd like to get this thing ready ahead of time and take it up to Leopard before I have to update to 6.0.
Is there a recommended order of upgrading in a situation like this? I would assume:

1. Down the ZCS services.
2. Perform normal upgrade to 10.5.x Server, verify normal/proper OS operation.
3. Install 5.0.16 OSE over existing 5.0.13 OSE.
4. Run update/install script.
5. Bask in continued Zimbra gloriousness.

That seem correct?

Yes, that seems good with the added proviso of plenty of backups between each step.
