## Upgrading from v1
1. Write down the current migration version from schema_migrations
1. `DROP TABLE schema_migrations`
2. Wrap your existing migrations in transactions ([BEGIN/COMMIT](https://www.postgresql.org/docs/current/static/transaction-iso.html)) if you use multiple statements within one migration.
3. Download and install the latest migrate version.
4. Force the current migration version with `migrate force <current_version>`.
Redshift is PostgreSQL compatible but has some specific features (or lack thereof) that require slightly different behavior.
