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".

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a critical decision framework for Prisma ORM users on MongoDB. Because Prisma 7 does not support MongoDB, v6 is the final classic-ORM version for this database. The skill guides users through the transition to Prisma 8, which currently offers MongoDB support in Early Access. It emphasizes that users should not attempt to upgrade to Prisma 7 and provides a structured approach to evaluating whether to migrate to Prisma 8 or maintain a stable v6 environment based on specific project requirements and technical blockers.

What it does

  • Explains the version landscape for MongoDB support in Prisma ORM.
  • Provides a decision matrix for choosing between migrating to Prisma 8 or staying on v6.
  • Outlines hygiene practices for projects choosing to remain on the v6 maintenance line.
  • Maps common v6 client API calls to their Prisma 8 equivalents.
  • Identifies technical blockers such as multi-document transaction usage.
  • Offers a verification checklist for the cutover process.

When to use it

  • When a user asks about upgrading a Prisma MongoDB project to version 7.
  • When evaluating a migration path from Prisma v6 to Prisma 8 for MongoDB.
  • When determining if a project is ready to move to Early Access software.
  • When needing to map existing v6 MongoDB client code to the new Prisma 8 API.

Advantages

  • Prevents invalid upgrade attempts to unsupported versions.
  • Provides clear, actionable criteria for assessing migration readiness.
  • Reduces risk by identifying specific code patterns that require refactoring.
  • Ensures stable maintenance for projects that cannot yet adopt Early Access features.

Usage examples

“Should I upgrade my Prisma 6 MongoDB project to version 7?”
The agent explains that Prisma 7 does not support MongoDB and directs the user to the Prisma 8 migration path, while checking for potential blockers.
“How do I handle transactions when moving from Prisma 6 to Prisma 8 with MongoDB?”
The agent clarifies that Prisma 8 does not yet have a native transaction method and provides guidance on using the MongoDB driver's session API.

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.

The version landscape

VersionMongoDB status
Prisma ORM v6Fully supported (mongodb provider); latest 6.x is the current stable path; maintenance line
Prisma ORM v7No MongoDB connector — not an option, ever
Prisma 8MongoDB support in Early Access through @prisma/orm-mongo; still changes between release candidates — the successor path for MongoDB projects

The decision, up front

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.

Note: this section will be updated when Prisma 8 adds a MongoDB transaction method.

If staying on v6: hygiene (a deliberate stay, not neglect)

  • Pin the Prisma packages to the latest 6.x line and keep taking 6.x patch releases.

  • Track Prisma release notes and security advisories for the 6.x line.

  • Keep the classic v6 MongoDB setup: url = env("DATABASE_URL") in the schema, db push workflow, no SQL driver adapters (see prisma-orm-setup for the v6 MongoDB shape).

  • Re-evaluate when Prisma 8's MongoDB support leaves Early Access, or when the blockers are resolved.

Verified against

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.

Hand-off rule

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.

Verification checklist for a v6 → Prisma 8 cutover: the data never moves — only the code does.

Priority

CRITICAL

Why It Matters

A v6 → Prisma 8 migration is a client and workflow migration against the same MongoDB database — there is no data export/import step, and introducing one (or pointing the new stack at a fresh database) turns a code migration into an outage. The checklist below keeps the cutover observable and reversible.

Ground rules

  • No data moves. The Prisma 8 contract is authored to describe the existing collections; both stacks read the same database during the staged phase.

  • v6 stays runnable until cutover is verified. Do not delete the v6 client, schema, or dependencies until the checklist passes.

Checklist

  1. Same database, verified: the Prisma 8 config points at the same connection string / database name the v6 app uses. The mongodb@7 driver rejects some URLs v6 accepted, such as AWS credentials in the connection string — validate the URL with the driver first.

  2. Server floor: MongoDB server is 8.0+ (Prisma 8's requirement; v6 tolerated older). Confirm before authoring any contract.

  3. Rehearsal on a copy: on a throwaway copy of the database, run contract emit, db update --dry-run, db update, and db verify, and confirm db verify passes before touching production. Verification failures here are contract-mapping bugs, not database problems.

  4. Index parity: enumerate indexes on every collection (db.collection.getIndexes()) and confirm the Prisma 8 contract declares the same set — v6 db push may have created indexes the new contract must re-declare, or verification and query performance will diverge.

  5. Validator impact assessed: Prisma 8 emits closed $jsonSchema validators by default; confirm legacy documents (extra fields, drifted shapes) pass them on the staging copy before applying to production.

  6. Storage-name addressing audited: every ported call site uses collection storage names (db.orm.users), not model names (see schema-contract-mapping.md).

  7. Transaction inventory mapped: grep the v6 app for $transaction; each hit gets a mongodb driver-session equivalent on a replica set (see client-api-mapping.md).

  8. Raw call inventory mapped: every $runCommandRaw / findRaw / aggregateRaw call has an explicit Prisma 8 replacement (db.raw, db.query.rawCommand(...), the pipeline builder, or the shared MongoClient).

  9. Staged read-only soak: run the Prisma 8 stack read-only against staging/production data alongside v6 and compare outputs before allowing writes.

  10. Cutover + rollback: switch writes to Prisma 8 only after the soak; keep the v6 branch deployable as the rollback path. Rolling back is a code rollback — the data was never moved.

After cutover, follow the synced prisma-8 skill for ongoing work (see the hand-off rule in SKILL.md).
