Yes, it will work partially. To make the switchover complete you need
to do a 'yum distro-sync full' afterwards. While I agree that a
reinstall is cleaner, that isn't a direct answer to your question.
You also have to re-install *every single package*, especially those
that may have minor, uncertain differences between the two
repositories. It can be done, I've done it between CentOS and RHEL and
back several times on the same environment.
This is what 'yum distro-sync' is supposed to do (distro-sync full works
based on the package checksums, and is supposed to reinstall every
single package that has a different checksum than the currently
pointed-to repos). If it does not do it properly, it's a bug that needs
to be filed against the upstream yum.
It's a very expensive process in terms of system resources and local
bandwidth.
It is that (In my case the new repos were on iSCSI SAN and the process,
while still taking quite a while, completed smoothly on all three Altix
systems on which I tried it).
