Given that none of the answers mention it, this is the gem that does the job: https://github.com/jalkoby/squasher

It basically reruns the migrations from scratch until the date you specify, and then loads the resulting db/schema.rb into an initial migration that replaces the old ones. It can also cleanup the schema_migrations table so you don't get those

entries when running rake db:migrate:status.
