upgrading ubuntu

[David]

I have an ubuntu 6.06 LTS (all updates applied) server that I need to  
upgrade to 8.04 LTS.   I've read the upgrade instructions,
I have the iso, I'll have the time this weekend.

Other than my custom kernel, are there any other gotchas I might need  
to worry about when I do the upgrade?  I do plan
on backing up config files, important data, etc prior to the upgrade.

Thanks,
David
