Migrationsstatus

Migrationsstatus is a concept used in software development to describe the current state of a collection of database and data migrations. It denotes which migrations have been applied, which are awaiting execution, which have failed, and which have been rolled back. Operators typically maintain a migrations registry—either in the database, in the version control system, or in the deployment tooling—that records the status of each migration along with metadata such as identifier, description, timestamp, and environment.

Statuses commonly include Applied, Pending, Failed, RolledBack, and Skipped. The status informs deployment decisions, rollback strategies, and progress reporting in CI/CD pipelines. A migration plan is considered up to date when all required migrations are in the Applied state across the target environment. In many frameworks, the migrations table or registry is used to compute the current migrationsstatus by comparing the desired set of migrations against those recorded as Applied.

Managing migrationsstatus involves handling drift between environments, partitioned migrations, and long-running data migrations. Best practices include keeping migrations small and idempotent, separating schema and data changes, using transactions where possible, testing migrations in staging, and recording robust rollback information. Tools typically provide commands to apply pending migrations, roll back last migrations, or re-baseline when necessary; they also offer dashboards or logs that expose the current migrationsstatus.

While the exact implementation of migrationsstatus varies by framework (for example Django, Rails, or Liquibase maintain their own registries), the underlying concept remains consistent: a reliable, observable record of the evolution of a database schema and its data over time.
