Microservices, essentially.

It's not really 1 x ten year project as such, but heaps of smaller 3-6 month projects (many running in parallel) to add chunks of new functionality (as microservices) and rewrite parts of the monolith that we can cleanly cleave off.

New parts of UI that are needed don't get added to the Delphi app, but get built as web pages (using React mostly at the moment), which get launched in Chrome windows from the Delphi application.

One day our Delphi app will be an empty shell of it's former self and we can have a huge decommissioning ceremony (party!), but that day's still a long way off... :)
