Upgrade from AIX 5.3 to 6.1

Hello Folks,
i am facing some weired issues.
case is like this :-
initially i was on AIX 5.3
i have installed filesets related to my application and those were in APPLY state.(COMMIT is set as NO)
Then i have taken lslpp -l| grep -i <apps name>
in that i confirmed whether the filesets are in APPLIED state or not. They were in APPLIED state. I have created some data.
Now i upgraded the system (5.3) to aix 6.1 and after upgradation i checked the lslpp o/p the it was showing the same filesets (which were in APPLIED state in 5.3) in COMMITED state.

Because of this i am not able to add new filesets even though using "OVERWRITE option which is set as YES."

Any pointers why this is happening ?
ideally the filesets should be in APPLIED state.

That happens during each and every upgrade and works as designed

no matter if the previous packages are applied or committed, this will not prevent you from installing (apply OR commit) newer versions of existing software? I would rather think that your packages are checking for AIX 5 and don't find it and that prevents you from installing new packages?

Kind regards
