This will sound terrible, but I am still using Eagle 3.55 for many of my designs, and have been pretty happy with the things I have been able to accomplish in it. For many years I have been meaning to upgrade, and finally this summer I want to upgrade to the latest Eagle, but I am not certain how best to bring my existing work forward. Is there a way to import my files from 3.55 to 7? I have hundreds of designs that I want to import so that I can continue to use upgrade them.
