The Applications System names per the APPL_TOP and the database are different

Sandeep reported this error after cloning:

The Applications System names per the APPL_TOP and the database are different.

Beginning database cleanup for previous session ...

Completed database cleanup for previous session.


The Applications System names per the APPL_TOP and the database are different.

Applications System name per the APPL_TOP: UAT11i

Applications System name per the database: PRD11i

If you continue, the Applications System name per the APPL_TOP will be ignored.

Do you wish to continue [No] ?

He solved it by doing this:

update FND_PRODUCT_GROUPS
set APPLICATIONS_SYSTEM_NAME ='UAT11i' ;
commit;

I am not sure why the name of the production instance remained in FND_PRODUCT_GROUPS inspite of running adcfgclone.pl and executing FND_CONC_CLONE.SETUP_CLEAN.
