    There is no "Ubuntu 10" or "Ubuntu 12". A new release is made every 6 months, in April (04) and in October (10), so there are 2 possible "start" versions - 10.04 and 10.10 and two possible "target" versions - 12.04 and 12.10. The answer is very different depending on which versions you have. Please edit your question to specify correct versions.

You can not upgrade an arbitrary version of Ubuntu to any other arbitrary version. For "normal" releases which are made every 6 months the upgrade procedure works only from release N to N+1 (e.q. from 10.04 to 10.10, from 10.10 to 11.04 and so on).

The Long Term Support (LTS) releases are made every 2 years and you also can upgrade one LTS release to the next LTS release. 10.04 was an LTS release, so you can directly upgrade it to 12.04, which is also an LTS.

Then you can either stay on 12.04 and upgrade it to 14.04 when it is released (in April 2014, supposedly), or to upgrade 12.04 to 12.10 now, but in this case you'll have to upgrade your machines every 6 month to stay on top.

  • 10.04 and 12.04 are LTS releases. 10.10, 11.04, 11.10 and 12.10 are not LTS releases.
