Ruby Rails 5.2 To Ruby Rails 6.0: How GitHub Made The Transition And Is It Worth Upgrading In 2020?

For a better understanding of this blog, it is important that you know what is Ruby on Rail (or Rails). So, anyone not familiar with it, understand it first, here. 

Ruby Rails is a powerful web development framework. It contains libraries that comprise ready-made codes that save developer’s time. 

By using this framework, the developer needs not write complete lines of code for various things. This includes forms, about us page, etc. 

Now, let’s get back to our topic of concern, how GitHub upgraded Ruby Rails from 5.2 to 6.0. 

GitHub’s migration from 5.2 to 6.0

GitHub is the world’s 65 most visited site and is visited by over 2 million companies worldwide. Last year, when GitHub finished with Rails 5.2, it started the up-gradation process to 6.0. 

And in this 6.0 upgrade, GitHub was more involved than ever. GitHub added many new features to the Rails while upgrading it. 

For example, default support to multiple databases. Therefore, GitHub doesn’t just upgrade the version only, it upgraded the Rails. 

Is it worth the headache upgrading to Rails 6.0 from Rails 5.2?

So, now this is the most obvious question to answer. Whether move on to the latest version or continue with the former one. 

So, let me answer this. In our opinion, it’s worth headache upgrading to 6.0. Upgrading from 5.2 to directly versions 7.0 or 8.0 can be difficult.

So, it’s better to upgrade Ruby Rails frequently. Moreover, this 6.0 update is promised as being the safest update by the company so far. 

So, the practice shows that it’s worth devoting a few moments of your time for shifting everything to the latest Rails version. Along with this, fix any issue(s) that comes up along your way. 

For any software that isn’t under current progress, by upgrading, you aren’t adding a new feature. It won’t affect anything. 

But just remember that by not upgrading, you are creating a technical deficit for yourself. Because at last, your dependencies won’t be supported and nobody will provide a patch for it. 

Hence, be it eventually,  some dependencies will suffer from drastic security exposure and will release a fully working fix. But only in an edition that operates in Ruby Rails 6.0 or 6.0+.

Rails application upgrade is a perfect time to test the app

If you are a developer, you must know how to upgrade applications from one version to another. If you’re a Rails developer, you need to accept the fact that in Rails, app’s version up-gradation is difficult. 

So, considering the positive reviews about Rails 6.0, will it enhance the above task? Or will it make the software extra reliable and faster? 

I would say, not significantly. But with no choice left and harms of not upgrading, you better upgrade it. 

But there’s another advantage of the latest version. Upgrading Ruby Rails app gives you an opportunity to explore the gems you’ve been using. 

Further, you get to learn about code reloading and character encodings. So, it helps you to deepen your understanding of Rails, Ruby, and your app’s background.


So, this blog makes sure that upgrading to Ruby Rails 6.0 is like a mandatory thing for the developers. Because with each passing time and updates, older dependencies will stop working. 

The new versions will not support them. Plus, how would you expect new engineering talents to be a part of your team if you’re using old technology? 

If you’re a competent Rails engineer, would you like to work on an application that isn’t using new Rails? Or if it doesn’t have any plan to upgrade? 

Definitely not! You would aim to be part of a team that works with/on new technologies. You would select a team that cares about upgrading and staying current. So, the last choice is up to you!
