Creating content migrations in Craft CMS | nystudio107

A useful primer on how to use migration files in Craft.

Migra­tions are PHP files that con­tain code which alters the data­base from one state to anoth­er.

The core commands are as follows.

Run any waiting migrations, specifically the safeUp() functions:

php craft up

Rerun the last migration (undoes the previous migration and runs the file(s) again, so any changes are automatically applied):

php craft migrate/redo --interactive=0

Revert the previous migration (runs the safeDown() function):

php craft migrate/down --interactive=0
