Red hat linux compatibility

Working on migrating Open PBS scheduler operating system from Centos 7 to RHEL. Is RHEL 8.9 is compatible with Open PBS version 20.0.0? Please advise

Yes it should be compatiable
Any reason for not trying the latest release.

I am trying to upgrade OpenPBS version 23.06. But unable to find package for RHEL. Packages are only available for Ubuntu, Rockylinux and Open Suse. Is there a link to provide update instructions and download link?

Could you please try the source code

I installed on RHEL using source tarball with no issues.
