Example systems and methods of upgrading a single-database, multiple-tenant software system are presented. In one example, a target database schema for a target version of the software system is created. For each tenant of a current database schema for a current version of the software system, a current state of the data corresponding to the tenant in the current database schema is captured. The data corresponding to the tenant is transitioned from the current database schema to the target database schema. The tenant in the target database schema is tested to verify the tenant. If the tenant in the target database schema is verified, the tenant in the target database schema is opened for users. If not verified, the tenant in the current database schema is restored using the captured state. |
