How auto rollback on rails work?

After git checkout:

1. Execute git checkout <previous-branch> db/migrate
2. Get migration versions
3. Execute bundle exec rake db:migrate:down VERSION=<version> for each version
4. Undo all changes in db/migrate/ and db/schema.rb

The flow will be less complicated if pre-checkout git hook exist

Note

• Assumes all migration are reversible
• bundle exec rake db:migrate:down VERSION=<version> fails silently
