Unloading BusinessPackages from Portal

Hi Everybody,

I have loaded a BusinessPackages into the Portal.(EP6.0)

Now, I want to unload the BusinessPackage(i.e the iviews,pages,worksets,Roles).

Is there a way out to identify and delete the above folders?.

In EP6.0 it's o.k. Suppose the BusinessPackage is related to EP5.0, all the folders will be stored in common under Migratedcontent/EP5.0.

My question is

" Is there anyway to identify the iviews,pages,worksets under these packages as these folders contains pages,worksets... related to other BusinessPackages?"

Apperciate anyone's help.

Thanks for your time.

Regards,

Vasu.
