My company is finally going to upgrade our TS system from 7.5 to 16.4.X. One of our major concerns is the backward compatibility with our legacy wfts, tpls, and custom IPLs. Has anyone used legacy wfts, dcts, tpl in the newer 16.4 systems? Of course I do expect some pains in getting the legacy stuff ported over, but I'm just looking for any suggestions on this path.
