5.0.8NE & Ubuntu 6.06 downgrade to 5.0.9FOSS Ubuntu 8.04

[quietas]

OK, here's the deal: 60 day trial x2, server put on hold x3, Craigslist server bought x1, NE installed x2, NE Purchase OK'd. Cash put out = 0.

Essentially my execs have OK's the install we moved over and had a trial extended while they gathered funds. Now I'm in the position that trials are running out and I plan to move to FOSS until my people get their stuff together.

What will be the easiest way to move from 5.0.8 NE to 5.0.9 FOSS, and Ubuntu 6.06 to 8.04?

You have several options depending on how you want to combine actions (like 5.0.8 > 5.0.9 & NE > FOSS switch in 1 or 2 phases) - if something should go wrong it's often easier to troubleshoot spread out steps. Platforms you can change 'easier' you can't downgrade ZCS version's easily. Take backups of course.

Platform change methods:
A) NE backup/restore Backup and Restore / Network Edition Disaster Recovery - Zimbra :: Wiki (changing servers)
B) ./install -s trick (using rsync or other backup method) Moving ZCS to Another Server » Zimbra :: Blog (see step 3)

Also have to decide if you want to do new Ubuntu 8.04 install or Ubuntu 6.06 > 8.04 in-place upgrade

Options:
5.0.8 NE > Platform change > 5.0.8 NE > 5.0.9 NE > 5.0.9 FOSS
5.0.8 NE > Platform change > 5.0.8 NE > 5.0.9 FOSS
5.0.8 NE > 5.0.9 NE > Platform change > 5.0.9 NE > 5.0.9 FOSS
5.0.8 NE > 5.0.9 NE > 5.0.9 FOSS > Platform change (NE method not possible) > 5.0.9 FOSS
5.0.8 NE > 5.0.9 FOSS > Platform change (NE method not possible) > 5.0.9 FOSS

In short the 5 options above depend on what you're itching to do first based on your timeline.

Also if you're changing architectures in there:
Exporting and Importing Zimbra LDAP Data » Zimbra :: Blog
Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki

First and foremost, if extension or cash does not come through in time I'll need to move from NE to FOSS. All others are wants rather than needs.

So either 1 or 2 phase:
5.0.8 NE > 5.0.9 NE > 5.0.9 FOSS
5.0.8 NE > 5.0.9 FOSS
