What is the proper way to downgrade from 7.3 to 7.2 ?

Hi:

I was trying to downgrade RHEL server from 7.3 to 7.2 by yum history undo, but I've hit an error :

$ yum history undo 69

RHEL 6 had # yum downgrade redhat-release https://access.redhat.com/solutions/186763

Also works on RHEL 7.

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.

thanx Wachira, I decided to wipe out the 7.3 install and install 7.2 fresh. Sometimes time is not on your side, the customer does not care how I get it done, they just want the end result :-) Pamoja Kabissa!

At the end of the day, you got the desired result. Ni Furahi day!

That just downgrades the redhat-release package...

Correct. All the updated packages need to be downgraded first before downgrading redhat-release package.

Your question leads to MY question : Why does someone want to downgrade a new point release to an older point release within a major system edition/version ? This makes absolutely no sense, RHEL 7.3 includes many bug fixes and a lot of improvements over RHEL 7.2 !

Hi:

What about our software performance degraded more than 50% after upgrade? Is it a good reason?

Regards J

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 ! :)

thank you everyone for your input. I decided to do a fresh install of 7.2 instead of trying to downgrade the 7.3 install.
