10,000+ tests. From 40 minutes down to 4.

The recipe: Rails 2.3 to 8.1, Ruby 2.5 to 3.4, Test::Unit to Minitest, factories to fixtures where it made sense, then parallelization.

The time to migrate is now. We know that other platforms will continue to innovate, while Heroku will lag behind (as they've been doing for years now)

RIP Heroku. You led the way for many years and you inspired all of us to simplify things that were really really complicated. Thank you for it all!

Why excited?

Because this is something that we've done in the past and we have a process that has been battle-tested on hundreds of applications.

We know we can help companies migrate in an organized way that will be seamless to their customers and engineering teams.
