    all this goes into the equation. generally you face 3 options:

    - total manual rewrite (expensive, slow, risky)
    - re-hosting, where you recompile the code on a different platform.
    to my knowledge, not existing for tandem/hp ns. sorry!
    - generative rewrite - analyze/generating into terrible java code - hit and run by indian consulting firms. VERY dangerous.

    none of them are great. they are all terrible. looking for the "best" exposes your lack of experience. there is no best, just the one with the seemingly smallest downsides.

    If it's well documented transaction processing in 21st century is not very expensive exercise with modern technologies e.g. https://nuodb.com/ just to mention one reasonable of alternatives.
    BUT nobody talked about requirements and documentation 30+ years ago only IBM consultants ...

    There is no such thing as

    HP Non Stop Tandem


    Those disappeared in 1995 .

    Everything HP touches DIED .
