Hi Douglas,
Export PADS ascii from either tool. Import the ascii in a non-integrated PADS flow and place the part in your design (I usually just do it through ECO mode). Create a new integrated PADS flow. Copy the part / decal from the non-integrated flow and paste it into the integrated flow via the ECO mode. You will then be able to right click on the part in your integrated design and save it to your integrated library.
