Comments on How to Update a Ubuntu LTS release to the next LTS Version (release upgrade)
This document describes how to upgrade from Ubuntu 12.04 to Ubuntu 14.04 LTS. Generally, the Ubuntu .04 versions that get released every 2 years are Long Term Support (LTS) releases, for instance Ubuntu 12.04, 14.04 etc. Effectively, this means that the LTS release comes supported with bug fixes and security updates for as long as 5 years, hence users would not have the privilege of being alerted through popups urging them to install the latest available version.

Please, do not call it dist upgrade. Call it (release upgrade)
# apt-get dist-upgrade
!==
# do-release-upgrade -d
i have 10.04.4 LTS. if i will do "do-release-upgrade" will it upgrade to 12.04 or 14.04. ?
Thanks! Just what I needed :)
The upgrade process will remove any PPAs, so you'll want to research any applications/servers that use those and ensure the programs have been ported to the newer LTS. Putting the new PPAs in after the update (hard to call some of these things "upgrades"). I 100% agree with Ivo's comment. On Ubuntu dist-upgrade is within the same release - newer kernels usually. I run a dist-upgrade as part of my weekly patching for 20+ servers here - no chance it will migrate from LTS-to-LTS.
