LGTM

you've got a typo here in the class name - but on another point, normally with migration file naming, the standard is to use the present tense, and use words like 'add', 'create', 'remove' etc (you can take a look at the older migrations for some good examples - something like AddEarlyResultTypeToCompletedUserJourneys)

Also you are probably already aware of this but just in case - to generate these files you can run some commands, which give you a nice file template to work with i.e. rails generate migration ChangeCompletedUserJourneys.

Other than the naming, looks good!

Closing this as having issues with pods and migrations.
