Prisma MongoDB Upgrade Path

MongoDB projects are the one Prisma cohort with no road into Prisma 7: v6 is the terminal classic-ORM major for MongoDB, and v7 never ships a MongoDB connector. The successor path is Prisma 8, where MongoDB support is in Early Access while PostgreSQL is a release candidate. The official Prisma ORM 6 to 8 (MongoDB) guide is the source of truth for the migration steps. This skill frames the real decision — migrate to Prisma 8 (the encouraged path), or stay on v6 where a hard blocker applies — and carries the migration mechanics.

Never do either of these:

• Never advise a MongoDB project to "upgrade to Prisma 7". The connector does not exist there. The prisma-upgrade-v7 guide does not apply to MongoDB projects.
• Never solve the version question by rewriting the app onto a SQL database. Changing the database engine is a separate, much larger decision that is not yours to make implicitly.
