If you are upgrading from an environment with a single instance of Shared Services (Release 11.1.1.3), perform the upgrade as documented in Upgrading Checklist.
Perform the upgrade for Release 11.1.1.3 products first. Note that you must configure Foundation Services first. Next, perform the upgrade tasks for all Release 9.3.3 products.
Note: | If you are upgrading multiple instances of Essbase, for each instance that you are upgrading from, you must create a new instance in Release 11.1.2.1. |
