Preparing to Upgrade

Ensure that the host on which you are upgrading SAP Mobile Platform is ready for you to begin the upgrade.

1. Prevent backups from interfering.
   You can either exclude the existing SAP Mobile Platform installation directory from backups or temporarily disable then.
2. Prevent system upgrades from interfering.
   You can either exclude the existing SAP Mobile Platform installation directory from system upgrades or temporarily disable them.
3. To accommodate SAP Mobile 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.
4. Verify that you have Administrator privileges on the upgrade target host.
5. Shut down all Sybase and SAP software, Sybase and SAP 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 SAP Mobile Platform services are: “SAP Control Center” and all services with names that begin with “SAP Mobile…”

6. 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.
7. For Windows 8 installations, 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 the SAP Mobile Platform Runtime.
