Hi folks.

I have 4 SLES 12 SP1 installations which do not have internet access.

I need to patch these to the latest Security Patches on a regular basis, also functional patches.
For example, security patches come out for September, I would patch them a week after the release.

I've tried to find information on how best to do this, but I haven't managed to find it.

So, right now I need to update these four servers from the Sp1 distro patch level, right up to the latest available patches.
From then on, it would be a monthly catch-up.

Would someone please advise what is the best way to do this please?
