Migrating From Merb to Rails 3

The Rails and Merb development teams merged to create Rails 3 in 2008, but while those competing teams merged, their frameworks didn’t. Though Rails 3 shows plenty of influence from Merb and its creators, today Merb itself is a legacy framework, with no clear, supported path for Merb apps to move forward to Rails 3 without significant effort.

This video presents experience gained in a Merb to Rails 3 migration, discusses the processes and tools used to make the migration possible (including Rack and RSpec 2), shares some issues encountered during this process.
