Most people and companies that we talk to about upgrades assume that we generally help organizations that need to migrate to the latest Rails version.

However, this isn’t necessarily the truth. Instead, we mostly perform Rails upgrades for companies who are all the way back on Rails 3 or 4. To give you a better understanding of how common it is for companies to be on much older versions, this is a general list of our statistics from the past few years.

• Rails 2.3 - 3.2: 5 - 15 upgrades
• Rails 3.2 - 4.2: ~40 upgrades
• Rails 4.2 - 5.2: ~40 upgrades
• Rails 5.2 - 6.1: ~10 upgrades
• Rails 6.1 - 7.1: ~10 upgrades
