Anyone has tried to Upgrade all the way from Ubuntu Feisty 7.04 to Trusty 14.04?

(I know the best way would be to get my data off the server and fresh install the latest release, but this is not the question here)

My guess would be to use the old-releases to upgrade step by step

  • from 7.04 to 7.10
  • 7.10 to 8.04.3 LTS
  • 8.04.3 to 10.04
  • 10.04 to 12.04
  • 12.04 to 14.04

I read this wiki manual for upgrading old releases But it doesn't say anything about directly upgrading from for example 7.04 to 14.04. But it seems like there a faster way to achieve this than updating step by step, is there? (see: Can I skip over releases when upgrading?)

What kind of problems would occur, If I go through all those steps especially from 7.04 to 14.04?

(sure I am sure, that there could emerge unsolvable problems so the system will end up in an unrecoverable state, so this would be just a try if it works)

I've done 8.10 through 9.04, 9.10, 10.04 to 12.04 in an afternoon.

The only "direct" upgrade (almost certainly the best and fastest route for you) is to get your data off the machine and clean install. It sounds nasty but honestly, it's probably going to be a better end result than anything else.

You can't skip normal upgrades because a package upgrade (especially when going from one release to another) is transformative. Scripts execute that update config files and move data around.

This works in a LTS setting because time and effort is spent working out what all those transformations are going to look like as one. That's just not a process that's sustainable for every little release.
