Upgrade SLES12 Test Server From SLES12_SP3 to SLES12_SP5
Issues are now occuring when trying to keep SLES12_SP3 up to date. It is now required to upgrade the SLES12 test server from SLES12_SP3 to SLES12_SP5 , so as to support the newer , more secure versions of SSL, particularly the TLS1.3 standard.
SLES12 system is currently disconnected due to too many issues on that version. We should look at whether we can continue to support this.
We have a docker container at test-docker-sles12-s390x-1 which is online and (presumably) usable. The physical machine test-marist-sles12-s390x-2 should potentially be decommissioned as it cannot easily be maintained. We do have a physical SLES15 system to test on non-containerised hardware.
