Run all plugin-migrations without installing them as real migrations in every app.
Add to your plugin's Gemfile and bundle:
gem "plugin_migrator"Rename the "db/migrate" to "db/plugin_migrate".
Run the following rake-task to run all missing plugin-migrations:
bundle exec rake plugin_migrator:migrate
Do rollbacks like so:
bundle exec rake plugin_migrator:rollback
