There is currently no automatic migration of data table changes from the dev to prod app. You have to recreate the data table changes yourself on prod.
There’s a cool utility to help you identify those changes. You may need to modify it for your use, but it gives you a good starting point. You’ll need to have both your dev and prod repositories cloned on your local machine to identify data table differences.
I use this utility with my dev/prod split and it works well.
