Before your OES2 SP2 servers are upgraded, make sure you complete the following steps.
If you plan to schedule immediate upgrades in Section C.6, Assigning the Bundles and Scheduling the Upgrades, you should do the steps now.
If you plan to schedule the upgrades to happen later, you have the option to do the steps later. Just make sure that they are completed before the upgrade process begins.
Make sure there are no Mozilla applications running on the OES2 SP2 servers you are upgrading.
On any servers that have the ZENworks Agent installed for the first time, check whether the SLES 10 SP3 and OES2 SP2 installation sources are listed in YaST Control Center > Installation Source.
If the sources are not listed, add them back before starting the upgrade. Otherwise, the upgrade pauses with a yast2 pop-up asking whether to continue, and manual intervention is required to complete the upgrade.
