Hi bwana Wachira, I am trying to downgrade a CentOS7.3 box to CentOS7.2. My customer said that he needs 7.2 for his testing. Do you know of any tool/procedure available for that?
Worst case is that I have to rebuild the box, probably 20 minutes?
thnx, Igeria
Bwana Igeria, downgrade can get messy. Not aware of any tools that will help you do it. If you absolutely must downgrade, then you will need a list of all packages which were updated then downgrade each one including the kernel. I've not tried this so I don't know if it works or not. Alternatively, provision a 7.2 box and migrate data to it. Tuko pamoja.
No - not a good reason, because software performance degraded more than 50% is an indication that most probably something went badly wrong during the upgrade process, which will not get fixed by a downgrade. You should try to repair what is broken or in case you don't get the issues fixed, perform a clean installation of RHEL 7.3 ! :)
