CentOS - Apr 2019 - In place upgrade of RHEL 8 Beta to CentOS 8?

I'm about to rebuild a server, currently running CentOS 6. If I have to do
an
OS reinstall, my intention is to upgrade, as it's the oldest OS server under
my purview. As this server is pretty low visibility, I'd like to see if I
can
start using EL 8 instead of 7.x. 

In the past, I was able to switch between different OS variants by simply 
changing out the yum.d files; EG: RHEL 6.x becomes CentOS 6.x by replacing a 
single RPM and doing a `yum -y clean all; yum -y update` without issue. 

How likely is it that similar functionality will exist switching from RHEL 8 
Beta to CentOS 8 final? Google pounding provided little info. I couldn't
even
find useful information for the transition from RHEL 7 Beta.

You are comparing 2 different things. What you are seeing is a
'finished' release of 6.x to latest CentOS-6 which is much different
from going from say RHEL-6beta to CentOS-6.
Betas of RHEL have normally had major changes between beta and final
versions. Going from EL6beta to EL6.0 or EL7beta to EL7 required some
manual work each time for anything beyond the base install because
packages were removed or settings changed majorly between them.

If you have the time to play around with it, then sure you might make
it work.. you might also wipe and reinstall.

There will not be any plan to do that, no.  Nor could you upgrade from
RHEL-8 beta to RHEL-8. They just don't build it with that in mind.

As Smooge said .. it might be possible.  But the whole point of the beta
is to allow for design changes.  The full package set was likely not
completely set, so some things could be removed or added and a bunch of
manual removals, re-installs would be required.  Different libraries may
be linked. Etc, etc.

I can't see almost any circumstance where I would recommend doing this.

Thank you. Gonna roll with 6 for a few more years then.
