Upgrade or Downgrad Centos 7.9 to be compatible with DOCA SDK for NVIDIA BlueField-2 DPU

[zux]

Hi all,
We have a server with CentOS Linux release 7.9.2009 (Core),
I want to install some software (NVIDIA DOCA SDK v1.5.0) but it says that my current version of Linux is not supported.
and per DOCA documentation they only support CentOS 7.6, 8.0 and 8.2.
can I do a downgrade or an upgrade to any of the supported version (mentioned above) without losing any of the data on the server?
P.S1: for now I am not allowed to do a clean install, only a downgrade or an upgrade.
P.S2: doing a: yum "downgrade redhat-release" results in "Nothing to do"

Keywords: NVIDIA, DOCA SDK, BluField, DPU, CentOS 7.6, CentOS 8.0, CentOS 8.2, Downgrade, Upgrade.

Those are all EOL releases that are riddled with security bugs and should not be used.

Try just editing /etc/redhat-release and changing it to say 7.6.

This. Software that does look up os version, does usually do it by reading that file.

Software that requires specific, outdated subversion is, IMHO, scary.


Overall, CentOS 7 is rebuild of RHEL 7. RHEL 8 is an entirely separate distro and there is no CentOS 8 at all.
Even if there were, there would not be upgrade from one distro to another.

The CentOS 7.9 is the only supported version of CentOS 7. Its repositories do not have pre-7.9 content.

is it about this: https://en.wikipedia.org/wiki/Nvidia_BlueField? This is pre-release hardware. If you have access to it, you also have access to the software. And if you are wondering how to get the software installed ...

There is a term for this kind of struggle, "PhD".

That should imply that the person in question is able and willing to seek and apply knowledge.

You found a place (this) and were able to apply what you found. Good.
