Scala 2 to 3 - Migrations are never easy

Was it going to be as bad as Python 2 to 3, or, Angular 1 to 2? We'll tell our story of how a small team of Scalaties ported a not "yet another todo/task list" product with ~10k LOC (not Scala as a better Java) project to Scala 3 in about two months. Yes, we had some Macros, and our project depended on many parts of the ecosystem, mostly cats/typelevel libraries. How did we plan and execute the migration? What went smoothly? What went very wrong? Which tools helped and where did we find help? All will be answered within these 45 odd minutes.Yes, there will be plenty of code as examples.
