Upgrade from 12.0.6 to 12.1.1

Hi Team

we are doing the upgrade from 12.0.6 to 12.1.1. We followed the note 752619.1.

Patches which are applied as per the note id,

8886260
7461070
8764069 in preinstall mode
Main Maintenance patch 7303030

After completeing the main patch we checked the release version from fnd_product_groups to confirm on the upgrade but still it shows the old version.

Are we missing something here?

SQL> select RELEASE_NAME,ARU_RELEASE_NAME from fnd_product_groups;

RELEASE_NAME  ARU_RELEASE_NAME
-------------------- ------------------------------

12.0.6                     R12

Please suggest.

Thanks
