Decision and migration guide for Prisma ORM MongoDB projects on v6, which have no upgrade path to v7. Use when a MongoDB project asks about upgrading Prisma, when "upgrade to prisma 7" comes up in a project with provider = "mongodb", or when evaluating a move to Prisma 8. Triggers on "upgrade prisma mongodb", "prisma 7 mongodb", "mongodb prisma migration", "prisma 8 mongodb".

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:
prisma-upgrade-v7 guide does not apply to MongoDB projects.| Version | MongoDB status |
|---|---|
| Prisma ORM v6 | Fully supported (mongodb provider); latest 6.x is the current stable path; maintenance line |
| Prisma ORM v7 | No MongoDB connector — not an option, ever |
| Prisma 8 | MongoDB support in Early Access through @prisma/orm-mongo; still changes between release candidates — the successor path for MongoDB projects |
Migrating to Prisma 8 is the encouraged path. MongoDB support in Prisma 8 is Early Access: functional and moving quickly — and the Prisma team wants MongoDB users to migrate early and share feedback. The migration mechanics are detailed in the references.
Staying on the latest v6 remains a legitimate choice where a hard blocker applies —
stated plainly: Prisma 8 has no MongoDB transaction method yet (multi-document writes use
the mongodb driver's sessions directly), and MongoDB behavior can still change between
Prisma 8 release candidates.
| Signal | Direction |
|---|---|
| No blockers below apply | Migrate to Prisma 8; run the verify-cutover-checklist and share feedback with the Prisma team |
| Greenfield / prototype / internal tool | Migrate to Prisma 8 |
Codebase uses multi-document transactions ($transaction) — check with grep, do not ask | Plan raw-driver session equivalents first (see client-api-mapping), or stay on v6 until Prisma 8 adds a MongoDB transaction method |
| Team cannot absorb breaking changes between release candidates | Stay on v6 until MongoDB support leaves Early Access |
| Risk-averse but interested | Point Prisma 8 at the v6 schema with prisma6Schema(...) (see schema-contract-mapping), rehearse on a copy (see verify-cutover-checklist), then migrate |
Note: this section will be updated when Prisma 8 adds a MongoDB transaction method.
url = env("DATABASE_URL") in the schema, db push
workflow, no SQL driver adapters (see prisma-orm-setup for the v6 MongoDB shape).| Reference | What it covers |
|---|---|
references/decision-stay-or-migrate.md | The full decision framing, blocker checks, and stay-hygiene detail |
references/schema-contract-mapping.md | v6 schema (mongodb provider, @db.ObjectId, composite types) → Prisma 8 contract concepts |
references/client-api-mapping.md | v6 client calls → Prisma 8 equivalents, incl. raw escape hatches and transactions — names map, parity does not |
references/migrations-mapping.md | v6 db push-only story → Prisma 8's plan/migrate/verify/sign flow |
references/verify-cutover-checklist.md | No-data-moves verification: same DB, index parity, staged round-trip before cutover |
Prisma 8 claims in this skill were checked against the
Prisma ORM 6 to 8 (MongoDB) guide,
written for @prisma/orm-mongo 8.0.0-rc.13, and the prisma-8 skill in
prisma/orm at commit
75c1460515fa2f11971533f6a1dec5dab35d4123. MongoDB support still changes between release
candidates: before acting on any Prisma 8 claim, check the installed version
(npm ls @prisma/orm-mongo) and its synced prisma-8 skill.
Prisma 8 on MongoDB requires Node.js 22.18+ (24.11+ on the 24 line; 24 recommended),
TypeScript 5.9+, MongoDB 8.0+, and mongodb@7 as a peer dependency. The mongodb@7 driver
no longer accepts AWS credentials in the connection string.
This skill is the discovery bridge, not a replacement for Prisma 8's own
documentation. After a project switches to Prisma 8, run prisma skills sync, read the
synced prisma-8/SKILL.md, and follow it for day-to-day work — do not keep working from
this skill's summaries.

Prisma ORM 7 CLI reference for existing Prisma 7 applications or explicitly selected Prisma 7 workflows. Covers prisma init, generate, migrate, db, dev, studio, and mcp. For setup, connection repair, or Prisma 8, use prisma-orm-setup; not the Prisma Platform CLI.

Deploy and operate apps on Prisma Compute with the Prisma 8 CLI. Use whenever the user mentions Prisma Compute, deploying or hosting a Prisma app, `prisma deploy`, `prisma dev module.ts`, Prisma Composer apps (`module.ts`, `compute()`, the `composer` section of `prisma.config.ts`), preview stages, deploy on push (`prisma git connect`, `prisma/cloud-deploy-action`), `prisma service` logs, versions, rollback, or custom domains, `project env`, `PRISMA_SERVICE_TOKEN`, regions, 504s, sleeping instances, or `waitUntil`; also when a project still uses the removed `@prisma/cli app deploy`, `prisma.compute.ts`, `defineComputeConfig`, `compute:deploy`, or `build logs` surface.
