SLES service pack upgrade
There are several ways to upgrade a SLES12 SP2 to SLES SP3.
OTC has not prepared the way of upgrading via SMT server.
The way to go in OTC is to change SLES repository configuration files to new service pack
and start dist upgrade with zypper command.
This upgrade process is the same for all SLES service pack upgrades.
An official desciption how it is done for SLES-15 can be found at SUSE website:

We prepared an example how to upgrade a fresh installed vm with OTC public image
Enterprise_SLES12_SP2_latest to service pack SP2.
- Please create a backup from you vm before start.
- Be carefull if you have own repositories configured. May better to disable them while upgrading the system.
Upgrade SLES12 SP2 to SP3
check os-release VERSION="12-SP2"
sudo cat /etc/os-release
update vm with last patches
sudo zypper ref
sudo zypper up -y
sudo zypper patch --updatestack-only
backup repo configuration
sudo cp -rp /etc/zypp/repos.d/ /etc/zypp/repos.d.SP2.backup
replace repo config for SP2 with SP3
cd /etc/zypp/repos.d
sudo mv OTC-SLES12SP2-LTSS.repo _OTC-SLES12SP2-LTSS.repo.disabledsudo sed s/SP2/SP3/g OTC-* -i
sudo sh -c 'for repo in $(ls OTC* |grep SP2); do newRepo=$(echo $repo | sed s/SP2/SP3/g); echo mv $repo $newRepo; mv $repo $newRepo; done
in case of additional configured repos do the same or disable them
sudo zypper refresh -f -s
simulate upgrade to SP3
sudo zypper --releasever 12.3 dup -y -D --no-allow-vendor-change
only continue if there are no errors in simulation
run upgrade to SP3
sudo zypper --releasever 12.3 dup -y --no-allow-vendor-change
reboot
sudo reboot
login to vm again
check os-release VERSION="12-SP3"
sudo cat /etc/os-release
