Upgrading from v1.0 to 2.0

Caveat 1: Not used db-migrate to migrate the unleash database

In FINN we used, for internal reasons, liquebase to migrate our database.
Because unleash from version 2.0 migrates the datbase internally, with db-migrate, you need to make sure that all previous migrations for version 1 exists, so unleash does not try to create tables that already exists.

How to check?

If you don't a "migrations" table with 7 unique migrations you are affected by this cavat.

How to fix?

Before starting unleash version 2 you have to run the SQL located under scripts/fix-migrations-version-1.sql
