Upgrade Apache 2.2-> 2.4 on COS5.2

Hi all

I know its EOL, but our 5.2 server has been so stable and the interruption of a upgrade/migration problematic, that we have deferred a complete server upgrade.

I just received notice from the security desk of our ISP that it is imperative we at least upgrade to Apache 2.4.23; this problem being that this is not in the repos, and would required spinning an rpm, trying a 3rd party repo, or compiling Apache. All fraught with risks, and which it seems to me will trigger other upgrades, ie PHP.

Has anyone by chance done this Apache upgrade?

Thanks
Ken
