Small issue after cloning

After I cloned my production system I faced the following error when I run adadmin or adpatch

"
AD code level : [11i.AD.I.4]


The Applications System names per the APPL_TOP and the database are different.
Applications System name per the APPL_TOP: clone
Applications System name per the database: prod

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

Do you wish to continue [No] ?
"
To solve it I had to run the following update statement on my clone database
update FND_PRODUCT_GROUPSset APPLICATIONS_SYSTEM_NAME ='clone' ;commit;


Hope that helped
