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.

Re: upgrade ->

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.

Re: upgrade ->

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:

Re: upgrade ->

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

Determining fastest mirrors [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host ''"

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: mlos2. Please verify its path and try again

Error during upgrade, rolling back


Upgrade to MLOS 2 failed. Please examine


for errors.

Checked named -- not running.

Attempted to start named and it failed to start with

kernel: named[27431]: segfault at 0 ip 00007f6ab7c89145 sp 00007fff4118f218 error 6 in[7f6ab7bc8000+1fb000]

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

Ran mwg-switch-repo and set it to

mwg-switch-repo --sticky

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!
