Upgrade path from 4.3?

[ghstridr]

I'm still running 4.3 and am wondering if there is a specific upgrade path or can I jump straight to the 5.x GA release?
I'm running it on Ubuntu 6 LTS

You be should definitely be able to upgrade from any of the 4.5.x's, but I'll consent that on average we test 4.5.10 > 5.0.1 upgrades more often as that's more common; plus there are some major tomcat & LDAP enhancements since 4.5.3, so even getting to 4.5.10 is a nice enhancement.
(Assuming FOSS because I didn't notice 'network' anywhere in the above or your prior posts.)
If you'd like to go 4.5.3 > 4.5.10 > 5.0.1 you can find 4.5.10 here: /community/downloads_previous.html & 5.0.1 through here: ZCS 5.0.1 is out!

Please don't forget to backup between each version - it may take longer or might be harder to do with your environment, but you'll be better in the end!

I seem to remember having to install using tar balls, not ubuntu deb.s
When I ran the 5.0.2 install script, it didn't find any of the installed zimbra pieces.
I did a dpkg -l and didn't see anything zimbra either. So as I think back, I believe I may have installed via tarballs.
I of course didn't do the install and had a fresh backup.
What are my options at this point?
