Can I update from a lower minor release to the current minor release. (a Solution)

Latest response

E.g. Can I update from RHEL 7.0 to RHEL 7.7 (current) or RHEL 8.0 to 8.1 (current)?

Yes you can. Unlike from 7.0 to e.g. 7.6 where you need some preparations.

A 7.0 to 7.7 (current) update only need the server to be registered to RHEL 7 repositories on your RH Satellite or CDN.

yum update will do the trick.

There are only few known issues.

  • Non Red Hat repositories that are not updated to the latest RHEL minor release
  • self compiled software with version locks.

Always make a full backup or Virtual Machine snapshot before every package update

Better safe than sorry

(side note it also work for each number lower than 7)
So we are talking about upgrading to the current release from an older release.
Thanks, Frederik Lindbergh for asking

Hi Jan Gerrit,

so when going from 7.4 to 7.7 it's possible to go direct to 7.7 and only one reboot?

Hi Fredrik,

Yes, it is possible ... just run sudo yum upgrade and reboot the system. :)

Hi Christian,

Now latest release in redhat 7 OS is 7.8 , So if we want to move from 7.4 to 7.7 what is the procedure ?

Hi Abdul,

Don't understand why you would want to do it - you can set the release server in the repo file.
Well, I've never done that, and I'm not sure if you need an EUS subscription to achieve this ... :)
