Upgrade OBIEE 11g catalog

I have been getting a warning in the OBIPS log:

OBIEE 11g: Warning: "Upgrade is recommended to the latest 11.1.1.6.0 (Build 120104.0800 64-bit) catalog version" After Upgrading to OBIEE 11.1.1.6

so i decided to upgrade the catalog:

Here are the steps:

Note: RPD should be consistent and take a backup of catalog before starting

Step 1: Stop OBIPS 

cd ORACLE_INSTANCE/bin

opmnctl stopproc ias-component=coreapplication_obips1

Step 2: find and set the tag UpgradeAndExit to true from false in instanceconfig.xml

<UpgradeAndExit>true<UpgradeAndExit>

Step 3: Start OBIPS

cd ORACLE_INSTANCE/bin

opmnctl startproc ias-component=coreapplication_obips1

Step 4:

After the catalogs are updated, edit the instanceconfig.xml file again and change the upgradeAndExit option back to false.

Step 5: Restart all services.
