The upgrade to Unwired Platform 2.2 is performed in place; this means that the files in the latest version overwrite the files in the earlier version.
Beginning with Sybase Unwired Platform version 2.1.1, the upgrade installer automatically adds Sybase SAPĀ® 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 Unwired Platform version 2.2 from Unwired Platform version 2.1.
