Upgrade-UX is an open source framework developed to assist in patching and/or updating Unix Operating Systems in a consistent and repeatable way. Especially in the industry it is forbidden just to run yum update (on Linux) to update your Linux system, therefore, upgrade-ux may proof to be a handy tool to guide you through the patching and/or update process as it follows a track you control (evidence gathering, pre/post executing of scripts, logging, and so on).
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:
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.
