Database migration is the process of transferring data and schema between database systems or versions. It covers schema evolution, data transformation, validation, and cutover strategies. The concept addresses compatibility, downtime minimization, and operational coordination across teams and environments. It informs planning, tooling, and rollback options.
Use this profile to understand the building block briefly, place it in the model, and switch to the 360° assessment when needed.
Theoretical construct: explains a term, principle, or mental model.
What organizes, connects, or makes decisions possible.
A database migration moves structure or data in a controlled way to another state.
Migration became recurring as applications evolved schemas and data across versions and platforms. The sources describe practice and Flyway, but no originator.
Preserve the starting state, version, transform, verify, and keep a recovery path. With live systems, compatible change order matters.
The topic has a specific mechanism and boundary that guide its use.
Its value depends on applying it to an observable problem and checking the result.
Migrations enable releases and platform changes. Backups, tests, order, and data volume determine outage risk.
