Prerequisite

According to the official upgrade guide, only two OS versions can be directly upgraded to SUSE 15 SP6. If you are not using SUSE 15 SP5 or SUSE 12 SP5, please upgrade to one of these versions before upgrading to SUSE 15 SP6.

Upgrading with Zypper

To reduce the installation size, it is suggested by the official upgrade guideline that two options have to be changed in /etc/zypp/zypp.conf.

  • solver.onlyRequires = true
  • installRecommends=false

 

To start the service pack migration, do the following:

  1. Register your SUSE Linux Enterprise machine if you have not done so:
    		sudo SUSEConnect --regcode YOUR_REGISTRATION_CODE
    		
  2. Start the migration:
    		sudo zypper migration -n --auto-agree-with-licenses
    		
  3. Restart your system after migration. The DSC in Network Engine should be able to compile the configuration, and your machine is now protected by the Network Engine.
