Oracle recommends that you uninstall earlier releases of EPM System products unless you want to maintain the earlier release environment. During uninstallation, when prompted whether you want to delete all the files and directories in the EPM Oracle home directory, select No unless you have moved your data to another location.
Note: | If you are upgrading on the existing machine, and you want to uninstall the earlier release, you must uninstall before you install Release 11.1.2.1. (Oracle recommends that you install Release 11.1.2.1 on a new machine.) You cannot uninstall the earlier release of Shared Services after you upgrade to the new release on the same machine. If you are upgrading FDM on the existing machine, you must uninstall the earlier release before you proceed. |
Tip: | If you choose not to uninstall the earlier release and you are upgrading on the existing machine, you might need to edit the PATH variable to remove all references to the earlier release. This can prevent you from reaching the character limit for the PATH variable when you configure. |
When you are done with this step, return to the Upgrading Checklist.
