Without knowing how many flights/hours involved it's difficult to comment, but I did a similar exercise once I had made the decision to go commercial. Took a while, but eventually got round to see most of the instructors/examiners who 're-signed' where appropriate.
For a while I carried the old copy as well to verify if requried, but never was asked to prove it.
