I part-own and manage a co-located server that is running Ubuntu 6.06 LTS server edition.
I realise that the version we use is supported until June 2011 (https://wiki.ubuntu.com/Releases) but I'm thinking of upgrading to 8.04 LTS.
This would be mainly to get the benefit of newer versions of software and also to hopefully resolve some problems we are having with software RAID.
Is it sensible to do an upgrade from a version that old or should I just do a fresh installation?
Upgrading would of course be better for me than doing a fresh installation as it would require less downtime.
But I had a bad experience with the desktop version of Ubuntu when an upgrade left me with a box that wouldn't boot successfully. Was this just bad luck or am I right to be wary?
A few things to note:
The server is patched and up to date security wise.
I'd take a full backup to a separate partition before doing the upgrade.
