So just... have the new server expose itself over the TN3270/TN5250 protocols, such that these interoperating systems see what they expect to see? (You could even build the new system as a regular REST API or something at its core, and then build the TN3270/TN5250 exposure as a separate gateway service on top, such that it'd be easy to shut it off later if everything finally moves off it one day.)
