The task Here at Redbubble we’ve been running Ruby on Rails since day one. We’re a small development team, so keeping up with even the latest stable release has been a struggle. Earlier this year we had a gap in product development and took the opportunity to move our stack forward. We’d been on Ruby 1.8.7 and Rails 2.3 for a year or two. After some investigation we decided we’d first move to Rails 3.0 which would make Ruby 1.9 an easier option. After significant library updates and code compatibility changes, we were ready to release Rails 3.0 on Ruby 1.8.7.
