To install Adaptive Server 15.0.3 over Adaptive Server 15.0.x server, perform these postinstallation tasks.
If you install 15.0.3 over a pre-15.0 Adaptive Server, then you must upgrade the server. The upgrading steps can be found in the "Upgrading Adaptive Server" chapter in the Installation Guide.
Before doing any of these tasks, source SYBASE.csh or SYBASE.sh in $SYBASE to set the environment variables.
