To the best of my recollection, there are few (if any) snags going from D3 to D6 for default VCL based applications. If it compiles there should be no problems running the .EXE.
If you're using any 3rd party components (especially share/freeware), you may have more trouble. If you have any without source code, then you may be dead in the water unless you can get updated versions for D6 or obtain the source for compilation. Back when I worked for TurboPower, our typical approach to a new version of Delphi was to load our product projects and attempt a build. We'd plow through any errors that arose, tweaking data types, altering parameter signatures, adding conditional defines, or whatever as needed. Best advice: try it, if you run into issues you don't understand, post them here. I'll do what I can to assist. Out of curiosity: What versions are folks on the list using regularly these days? A couple of years back, I was working for a company that was still on D6. Now I work for one using D2007 and do some additional side work for a company using XE7. Is anybody working somewhere that actually stays pretty up to date on Delphi versions?
