distrorejuve is a utility that helps with upgrading distros. It works on a number of different distros (Ubuntu, Debian, Centos). It uses apt, yum and repository corrections as appropriate. It can dist upgrade between multiple versions for Ubuntu and Debian.
To get the latest version of this script:
wget -O distrorejuve.sh --no-check-certificate https://raw.githubusercontent.com/pbkwee/distrorejuve/master/distrorejuve.sh
Example usage to dist upgrade to latest Debian or Ubuntu disto. First make a backup of your server. Then run:
sudo bash distrorejuve.sh --dist-upgrade | tee -a distrorejuve.log
- Enable archive repositories for older Debian distros
- Enable lts archive for Debian squeeze servers and old-releases for Ubuntu
- Dist upgrade Ubuntu distros to the next LTS version. Then from LTS version to LTS version.
- On completion provides information on config changes (modified config files, changed ports)
- Install missing Debian keys
- Handles a few common Apache config issues after a distro upgrade.
- Designed to run unattended without lots of prompting.
- Burgeoning support to cross grade 32 bit distros to 64 bit

Run with --to-next-ubuntu to get from an ubuntu distro to the next ubuntu version. If the current ubuntu is an LTS version then this skips to the next LTS version.
