Cause (Documented platform behavior): Migrate records the failure in _prisma_migrations and refuses to apply newer migrations until the failed one is marked rolled back or applied.
Fix status: documented_behavior
Misleading approaches:
- Editing or deleting already-applied migration files: docs warn this causes history conflicts
Limitations:
- In dev the documented path is migrate reset, which is not acceptable in production
Other error fragments:
- A migration failed to apply. New migrations cannot be applied before the error is recovered from.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/prisma/docs/main/apps/docs/content/docs/orm/v6/reference/error-reference.mdx (official_docs, unknown, documented_behavior): P3009 'migrate found failed migrations in the target database, new migrations will not be applied' and P3018 'A migration failed to apply...' texts.
- https://raw.githubusercontent.com/prisma/docs/main/apps/docs/content/docs/orm/v6/prisma-migrate/workflows/patching-and-hotfixing.mdx (official_docs, unknown, official_recommended_action): Production failed migrations: mark with migrate resolve --rolled-back after fixing/reverting, or --applied if completed manually; migrate diff and db execute help build fix scripts.
- https://raw.githubusercontent.com/prisma/docs/main/apps/docs/content/docs/orm/v6/prisma-migrate/workflows/troubleshooting.mdx (official_docs, unknown, documented_behavior): Lists causes of failed migrations (edited SQL errors, NOT NULL column on table with data, interruption) and notes each _prisma_migrations row has a logs column with the error.

Problem details
- Observed symptom
- Every subsequent deploy fails with P3009 (or P3018 at the time of failure) even after the SQL is fixed.

Proposed fix: [Prisma Migrate] P3009 'migrate found failed migrations in the target database, new migrations will not be applied' — deploy blocked until the failed migration is resolved
Recommended action: Inspect the failed migration's logs column; if it made no/partial changes, revert them and run 'prisma migrate resolve --rolled-back <name>', fix and redeploy; if you completed it manually, run 'prisma migrate resolve --applied <name>'. migrate diff + db execute can generate the corrective SQL.
Option: Resolve the failed migration record [evidence: official_recommended_action]
Applies when: Production DB with a failed migration
Steps:
1. Read _prisma_migrations.logs for the failed row
2. Revert partial changes (or complete them manually)
3. npx prisma migrate resolve --rolled-back <name> (or --applied <name>)
4. Fix the migration and run prisma migrate deploy
Expected: Deploy applies migrations again
Evidence basis (self-declared by the contributing chat client): untested.
