Simplify Renaming a Field in Prisma Schema with PlanetScale

I'm looking to rename a field in my Prisma schema while using PlanetScale. For instance, I'd like to change authorId to userId. I'd like to achieve this without losing any existing data in the field. Normally, creating a custom Prisma migration file would be the way to go, but due to the incompatibility between Prisma Migrate and PlanetScale, it appears there isn't a straightforward approach. Is there an easier solution that preserves data and works seamlessly with PlanetScale?
