What I Learned From My First Rails Upgrade

Before I started with OmbuLabs, I was primarily a front end/UI developer, working on building webpages with HTML, CSS, and jQuery, and some light web application development with WordPress. Though I had a solid grasp of software engineering fundamentals through the curriculum at Launch School, and I had gone through several Ruby on Rails tutorials to prepare for job interviews, I found that building my own apps didn’t prepare me for the upgrade process. With my own applications, I got to start from scratch using the latest tools in the Rails ecosystem. On the job I had to wade through large legacy applications that hadn’t been upgraded in years.Luckily my teammates had already written tons of articles, as well as an eBook, about FastRuby.io’s upgrading philosophy and process. I tried to read as many articles as I could before the client project started. But until you go through the process a few times, that knowledge is purely theoretical.
