As a development consultancy, we deal with a whole lot of projects: static websites, web platforms, intranets, mobile apps, etc. Some are bigger, and some are smaller, but all of them require maintenance.

This post is the first one of a series where we break down how to correctly upgrade a Ruby on Rails application.

In this first part, I am going to introduce you to the project and how we planned the upgrade minimising risks because the project is already live.

You're one step away from meeting your best partner in business.
