Hyperion HFM copy app from 11.1.2.2 to 11.1.2.4 and migration steps

We recently upgraded to Hyperion 11.1.2.4 and updated our HFM servers in Dev/QA/Prod to 11.1.2.4.205 patch level.

In order to bring my HFM application from 11.1.2.2 to 11.1.2.4, below are the steps we followed:

1- Run app copy on Dev 2.4 server using UDL from HFM 2.2 as source and Target HFM 2.4 UDL
2- Then run EPM system configuration on HFM 2.4 Dev server and select the option "Upgrade Applications from Earlier Release"
3- Then open the HFM 2.4 Dev Consolidations screen, register the app, provision the user and then the user can login
4- Run the app copy from Dev 2.4 to QA 2.4 and then QA 2.4 to Prod 2.4, since the app that was copied from 2.2 release is now in 2.4 format
