Performing an Upgrade From Sybase Unwired Platform 2.2.x to SAP Mobile Platform 2.3 SP04

The upgrade From Sybase Unwired Platform version 2.2.x to SAP Mobile Platform version 2.3 SP04 (also called a full upgrade) is performed in place; this means that the files in the latest version overwrite the files in the earlier version.

You can install SAP Mobile Platform version 2.3 SP04 directly, or upgrade directly from version 2.2.x, or 2.3.x.

Beginning with Sybase Unwired Platform version 2.1.1, the upgrade installer automatically adds SAP® Data Orchestration Engine Connector (DOE-C) if it does not exist in your earlier version installation, and upgrades DOE-C if it is present.

If you are upgrading to a support package or patch, see the ReadMe file for that support package or patch for instructions. This chapter discusses only upgrading to SAP Mobile Platform version 2.3 SP04 from Unwired Platform version 2.2.x.

Note: When upgrading, there is a potential issue with a Windows process holding a lock on one of the 12 Adaptive Server Anywhere (ASA) libraries (DLLs) even though all the ASA processes have shut down. This causes the upgrade to fail because the upgrade cannot overwrite the file. This is specific to a 32-bit Windows Server 2003 SP2.

Workaround:

Shut down all Sybase Unwired Platform processes.
If services were set to automatic, set the start up for the Sybase Unwired Platform services to manual.
Restart the system.
Run the upgrade after the system has restarted.
If step 2 was performed prior to upgrade, set the startup for the services back to automatic.
