Can I go

9.04 -> 10.04 -> 11.04 -> 12.04 -> 13.04

Or do I need to go 'through' minor versions, i.e.

9.04 -> 9.10 -> 10.04 -> 10.10 -> 11.04 -> 11.10 -> 12.04 -> 12.10 -> 13.04

    Besides it being a duplicate question ;) ... I would re-install. 1. Upgrading takes too long. 2. Upgrading will leave old, no longer used, files. 3. Upgrading a list like this has too many points of failure. – Rinzwind Oct 04 '13 at 12:49
  • And 4) 9.04 has not been supported since October of 2010. If you have really been running an unsupported, unpatched OS for 3 years, there is a very real chance your system has been hacked. – psusi Oct 04 '13 at 13:34

You can upgrade from LTS to LTS so in theory you could do:

9.04 → 9.10 → 10.04 → 12.04 → 12.10 → 13.04

I'm not sure if the 9.10 repo still exists though as it's been decommissioned for a couple of years already so that may throw a massive spanner in the works.

But even if it did, that amount of bandwidth and the time spent unzipping all those updates... You'd be better off just with a clean install. It's faster and means there's much less chance of running into dodgy configuration issues (which shouldn't happen, but occasionally do).

Another idea is to get to 12.04 and use one of the HWE stacks to get a fresher kernel, driver and graphics stack. I'm not sure what you're after exactly but 12.04 is solid and it gives you a simple upgrade path to 14.04 in 7 months time.
