Converting the Layout Libray 9.2 to Allegro PCb Editor 16.3??

Hi.

I am using the OrCAD 16.3. Me had worked fully with layout 9.2. But in my organization they told that use the Allegro PCB editor except of layout 9.2. 

My Problem is i want to convert my library files of layout 9.2 to allegro PCB editor 16.3.Later some time me had tried the conversion of files in layout 16.0 too.That also been get worked.So me need the details of converting the library files OrCAD 9.2 to OrCAD 16.3 files.

So provide me an better solution to do this. Because my library are too larger to create it.So only.
