Legacy Ruby on Rails

Rails 3, 4, 5 — old versions without security patches.

How Renovio modernizes Legacy Ruby on Rails

Old Rails has serious security issues. AI either steps each version up to Rails 7+, or migrates to Node.js / TypeScript when that makes more sense.

Typical signals you are in this bucket

  • Ruby 1.9 / 2.x
  • Rails 3.x, 4.x, 5.x
  • Unmaintained gems

Recommended target stack

Rails 7.2 or TypeScript + Next.js.
