Cause (Documented platform behavior): _prisma_migrations records migrations from the newer version as applied (or failed) while the actual schema differs; Prisma refuses to proceed after a recorded failure.
Fix status: documented_behavior
Workaround (not a fix): DATABASE_URL=... prisma db push (can drop data).
Misleading approaches:
- prisma db push without a backup - can cause data loss if the schema removes columns/tables
Other error fragments:
- New migrations cannot be applied before the error is recovered from
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/BerriAI/litellm-docs/main/docs/troubleshoot/prisma_migrations.md (official_docs, 2026-09-27, official_recommended_action): LiteLLM runs prisma migrate deploy at startup; after rollbacks, _prisma_migrations can hold stale or failed entries causing 'relation ... does not exist' or 'New migrations cannot be applied before the error is recovered from'; fix by deleting the failed entries and restarting, prisma db push as last resort.

Problem details
- Observed symptom
- Proxy fails to start or keeps restarting during migration after a rollback, or after a previously failed migration.
- Context
- Product: LiteLLM Proxy Component: Prisma migrations (prisma migrate deploy at boot, _prisma_migrations table) Operation: Upgrading, downgrading, or re-upgrading the LiteLLM proxy image against an existing database Affected versions: any LiteLLM proxy version using Prisma migrations Environment: LiteLLM proxy with DATABASE_URL (PostgreSQL) Packages: litellm proxy versions with Prisma migrations Trigger: Rolling back to an older version then upgrading again, or a prior migration failure recorded in _prisma_migrations.

Proposed fix: [LiteLLM Proxy + Postgres] Startup migration fails after a version rollback/re-upgrade: 'relation "LiteLLM_..." does not exist' or 'New migrations cannot be applied before the error is r
Recommended action: Inspect _prisma_migrations (unfinished or rolled-back rows, or rows from the version you rolled back from), delete the offending entries, and restart so LiteLLM re-applies them; use prisma db push only as a last resort after a backup.
Option: Delete failed/stale _prisma_migrations rows and restart [evidence: official_recommended_action]
Applies when: Rollback or failed migration states
Steps:
1. SELECT migration_name, finished_at, rolled_back_at, logs FROM "_prisma_migrations" ORDER BY started_at DESC LIMIT 20;
2. DELETE FROM "_prisma_migrations" WHERE migration_name = '<failed>';
3. Restart LiteLLM
Expected: Migration re-applied on boot
