If you want to take advantage of the latest security updates - then yes. Upgrading your Rails application ensures that you are not stuck with the bugs and errors of the previous version. You will also get enhanced stability in your app without changes in the coding structure. Rails migration is necessary to add the layer of security that will protect your application from the latest vulnerabilities that the earlier version of Rails is not prepared to handle. The latest Ruby on Rails version will also help to keep the RubyGems stable and functioning properly. You can hire a remote Ruby on Rails developer from BoTree and get started with migration today.
