Answer:
If certain things weren't done on a vendor and you are still using them, I would do it now or as the contract is renewed to continue their services. The preference would be on now, depending on the vendor and access they have to your systems and confidential information. If that vendor is no longer in business, no, I wouldn't go back. It serves no purpose assuming they wouldn't have your files any longer.
