Before you use ZENworks 2017 to upgrade the OES 2015 servers to OES 2015 SP1, you must have the following:
A ZENworks 2017 server installed and running in your network. For more information, see the ZENworks Server Installation Guide.
The ZENworks 2017 agent installed on each OES 2015 server that you plan to upgrade.
Each OES 2015 server registered with the ZENworks 2017 server.
Each OES 2015 server updated with the latest OES 2015 and SUSE Linux Enterprise Server, (SLES) 11 SP3 patches: SLES11-SP3-Updates-bundle (with install action), SLES11-SP3-Pool-bundle, OES2015-Updates-bundle (with install action) and OES2015-Pool-bundle.
After the SLES11-SP3-Updates-bundle and the OES2015-Updates-bundle install successfully, reboot the machine and then remove the OES2015-Updates-bundle and OES2015-Pool-bundle assignments.
