Porting the software is, by far, the easiest and shortest effort (as

I figure 3 man months for the whole exercise -- assuming domestic
sources are available for all components.  So, it should be
relatively easy to put a price tag on that effort -- even if
taken in anticipation of a future problem.

 There are companies that do such an analysis as a service, including
second sources and part end-of-life estimates. I can't recall a name

It integrates with major tools. You pay for the number of unique lines in the BoM, so it can "pay" to remove the typicals, that you are sure never will be a problem (surface mount resistors, caps etc)
