You must apply the maintenance release on top of your existing EPM System installation.
You must apply the maintenance release to all EPM System products in the deployment. You cannot apply the maintenance release to only some products.
If you are applying the maintenance release to move from EPM System release 11.1.2.0 to EPM System Release 11.1.2.1, or if you are reinstalling EPM System products, you must first stop all the services for EPM System products.
Note that you must manually stop the Integration Services service manually using the Task Manager.
If you are applying the maintenance release to move from Essbase Release 11.1.2 to Release 11.1.2.1, you must first export linked reporting object information from the 11.1.2 database, and then delete the linked reporting objects. After applying the maintenance release, import the exported linked reporting objects. See Essbase Maintenance Release Installation Prerequisites.
