how to update entire server without changing server OS version

Question

I am new to linux . I have to patch a new build server. The server is with hundreds of vulnerability thats why I am told to patch system . This server is 7.9 version and registered with satellite server . I am afraid If I will run " Yum update -y " this will update OS version from 7.9 to 8 since OS version is strictly needs to be 7.9 I have updated kernel recently using " yum update kernel*" My question is how to update entire server without changing server OS version

Thanks in advance

You cannot upgrade major versions of RHEL just with yum. It will always upgrade only on the same major version.

You must follow a specific procedure to upgrade RHEL 7 to 8. Just running yum is not going to do it.

You can run yum update without -y to preview the changes which will be made before you accept them.
