I would do it the opposite way.
Say you have part 1.ipt (which is at rev A.) Now a change has occured.
I would open part 1.ipt and do a saveas and call it part 1 rev a.ipt then make your change to part 1.ipt (leaving part 1 rev a.ipt as your fall back) Now you know your current part is always the one without the revision letter
Then your whole problem is solved.
Now your always working/constraining,etc.. the same part so a replace all is never needed.
We also use PDF's to keep old revisions of drawings. When a drawing is released I immediately print to pdf and save it with its rev number in the filename. So anytime I need to see an old rev's drawing I just go open the pdf. I do NOT save revisions of idw files only the pdf.
