Upgrade-UX is a software framework to update or patch lots of Unix systems (Linux, HP-UX, AIX and Solaris).

In professional environments it is not allowed to just blindly update an UNIX system without testing this first out on a development system, pre-production and so on. The upgrade-ux product allows you to repeat this process in a consistent way and as many times as you like on any system. Upgrade-ux understands two states:

• preview mode: will go through the whole process without actually doing the update
• upgrade mode: will do it for real (the update)

The upgrade-ux uses configuration files which describes what a particular Unix Operating System requires to be upgraded in the way you want it (or designed it). Doing it this way allows you to exactly define how a system should look like after the upgrade or patching. Nothing else can be installed, removed or configured.

Furthermore, many checks can be build-in via adding simple scripts. We also keep of each run an unique log file, and furthermore, we keep evidence before and after patching in a special directory. Months later we can still inspect these logs and evidence directories to verify what happened or what has changed in the meantime.
