Migrating a One2One field to a One2Man
Want to change my schema to make a specific field a One2Many[] now, is there a good way to roll this out without destroying all the existing ORM code

Hi @Philip 👋
To change your schema to make a specific field a one-to-many relationship without disrupting your existing ORM code, you can follow these steps:
1. Modify your Prisma schema to define the one-to-many relationship.
2. After updating your schema, regenerate the Prisma Client to reflect the new changes using the following command:
npx prisma generate
3. If you have existing data that needs to be migrated to match the new schema, you can write a migration script or use Prisma Migrate to handle this.
