can we import Data from standalone database to Apps database by creating one custom user?

Hi Experts,

   we have 2 database's in our environment. one is 11.5.10.2 apps database and other is standalone database which is used for 10gAS.

   both the Database's are integrated with Db links.


  My question is can we create one custom user in apps database and import the whole data from standalone database to that user?

  After importing whole data to custom user can we integrate 10gAS forms,reports to that user?

   Is this legal?



  Because now performance is unsatisfactory due to Db links.

   Is this legal?
