Do not run the update installer unless CA OM Web Viewer Version r12.1 is already installed on your system.
Back up your current CA OM Web Viewer according to your application server environment before you run the update installer.
The update installer replaces the <install_folder>\sampleExits folder. We recommend that you develop EXITs by using a copy of this folder outside the CA OM Web Viewer install location.
Important! If you have done EXIT development in-place, back up this folder to avoid losing your custom EXIT source.
