Preparing to Upgrade

Ensure that the host on which you are upgrading Sybase Unwired Platform version 2.2.x to SAP Mobile Platform 2.3 SP04 is ready for you to begin the upgrade.

1. Shut down all Unwired Server nodes in the cluster.
2. In the Windows Services control panel, check the startup type of all services with names that start with "Sybase". If any of these services are set to Manual, change the setting to Automatic.
3. Prevent backups from interfering.
   You can either exclude the existing Unwired Platform installation directory from backups or temporarily disable them.
4. Prevent virus scans from interfering.
   You can either exclude the existing Unwired Platform installation directory from virus scans or temporarily disable them.
5. Prevent system upgrades from interfering.
   You can either exclude the existing Unwired Platform installation directory from system upgrades or temporarily disable them.
6. To accommodate Unwired Platform internal communications, you may need to reconfigure intrusion detection/prevention systems (either hardware- or software-based).
   See Intrusion Detection and Protection Requirements in Landscape Design and Integration.
7. Verify that you have Administrator privileges on the upgrade target host.
8. Shut down all Sybase software, Sybase processes, and associated third-party processes running on the installation target host and all server nodes.
   

   Use the Services panel from Windows Control Panel to verify that services are stopped. The Sybase Unwired Platform services are: “Sybase Control Center” and all services with names that begin with “Sybase Unwired…”.

9. If User Access Control (UAC) is present in the version of Windows where you are installing, disable it. Restart the system for this change to take effect.
10. For Windows 8, verify that the Microsoft .NET Framework 3.5 has been enabled before starting the upgrade. If not enabled, you must manually enable the .NET Framework 3.5 from the Windows Features control panel applet before upgrading.
11. From the Microsoft Cluster Manager, make sure that the first data tier host is the active node.
