[ale] Is there a path out of the Centos 6 forest?

[Lightner, Jeffrey]

I learned long ago that doing in place upgrades of one major release to another for any OS are generally a bad idea:
1) They are often not supported well.  I'm pretty sure RH never "supported" the upgrade from 6 to 7 though they did mention that some people had said there was a way to do it.
2) No matter how much planning you do ahead of time you end of having niggling little issues to address after the upgrade.
3) The old release leaves many things behind and you're never quite sure later what is safe to delete.

Much better to take the pain of a new install than an in-place upgrade.   Another benefit to doing that is you can see a lot more of what the new setup does rather than trying to force the new release to do what the old one did.

IIRC, there is no in-place (yum-based) upgrade from EL6 to EL7; you need to reinstall (which I believe you can do in place without reformatting the disks).  I believe there WILL be a yum-based upgrade path from EL7 to EL8.
