Streamlining the Rails upgrade process on a large monolith  ↦

We recently upgraded our monolith application from Rails 6.0 to Rails 6.1. By evaluating our prior experience on Rails upgrades, we have streamlined the process and we want to share it with you.

In this post we give some insights on our workflow, from organizing such a milestone to actually delivering it without blocking an engineering team of more than 160 developers, building an application that peaks at more than 100k requests per minute.
