Doing testing of the new version of Librarian on the same LPAR with the Production v4.3 version of Librarian.
Can we access the same Librarian Master files with the new version for testing without causing problems for Production? 
Yes.  You can use Librarian 4.4  to access the same Master files used with Librarian 4.3 without causing any problems.
