Migration¶
Migration is the incremental upgrade of a piece of code.
It is often used for databases, for example, with Laravel database migrations; for components and frameworks: for example, CakePHP migration.
Usually, migration requires some action from the user, although a migration script may be provided.
Migration may also be called upgrades.
