Is there any specific issue you face which stops you from compiling old files?
As I mentioned in my other comment, my grad school days documents are still compiling fine.
If you still use LaTeX 2e and you've got all the dependency packages with you, pdflatex should Just Work. right? I can't remember any major change that would outright break your compilation. And I haven't seen such issue too myself. So I genuinely want to know what specific issues you or others face that wouldn't even let you compile your document.
