ruby - Any recommendation for a former Rails 2.3 users to migrate to Rails 5.x? -


this question has answer here:

i used program using rails 2.3.x heavily, has been while since coded. took managerial position of big company, , don't have enough time play old code. recently, realized need hone skill , start old web services , start there.

any recommendation me how started?

be aware multi-step process , can take long time. make sure test bugs after accomplishing each step since they'll appear.

  • the first step migrating rails 2.3 rails 3.0.
  • second want upgrade ruby 1.9.3.

  • pushing rails 3.0 rails 5.x covered railsguides has excellent documentation. you'll notice there number of interim steps:

    1. rails 3.0 -> rails 3.1
    2. rails 3.1 -> rails 3.2
    3. rails 3.2 -> rails 4.0
    4. rails 4.0 -> rails 4.1
    5. rails 4.1 -> rails 4.2
    6. rails 4.2 -> rails 5.0
    7. rails 5.0 -> rails 5.1

i suggest adding unit tests core features if don't have them. helps finding issues easier progress.
