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.

    Hopefully, not quite as long, given the work upstream was doing to make trouble for Oracle when they were building 7.

    But it’s not like I’m in a real rush…. This would be for home, for my workstation, for my antique (2009) HP Netbook (I use when I travel for email and news). Not sure what I’ll do when my new lady and I build her a new system, since she wants Linux.

  • It took 6 months to go from first beta to first release of RHEL 7, and this beta is now about 5 months old. So next month for sure. :)
