      What's the appropriate upgrade path from to


      The release notes say to use mwg-switch-repo, but that doesn't exist until 7.3.

          I havent been able to test this yet, but you can still use the 7.3 yumconf package, once installed, you will have the mwg-dist-upgrade and mwg-switch-repo commands available


          yum install yumconf-7.3-mwg

          mwg-dist-upgrade <version number>


          I'll give it a shot on one my VM's and report back.

            After running 'yum install yumconf-7.3-mwg' the 'mwg-dist-upgrade' command was available, but 'mwg-switch-repo' was not.


            In any case you should run the mwg-dist-upgrade anyways.


            Here is an example:

              yum install yumconf-7.3-mwg worked


              mwg-dist-upgrade wasn't as successful




              Towards the end of the process, this was reported:


              Loaded plugins: changelog, downloadonly, fastestmirror

              Checked named -- not running.


              Attempted to start named and it failed to start with

              Edited /etc/resolv.conf and pointed nameserver to a local (known working) namedserver.


              Ran mwg-switch-repo and set it to

              Creating repository configuration for Sticky MWG (release)

              Repository configuration has been updated.

              Now run "yum upgrade" to perform the actual upgrade.


              Ran yum upgrade


              Things seemed to go well, but post-upgrade I was no longer able to sudo.


              Logged in via GUI -- at least one screen said 7.3.2.


              Given the cumulative issues, despite the amount of pain it's going to cause, I'm now leaning toward doing a clean install of 7.4 for all of our MWG systems.


              Happy Holidays!
