# Rollbacks and recovery (/docs/orm/migrations/rollbacks-and-recovery) Rolling back is one more migration that makes the database match an earlier contract state. Recovery is fixing a failed migration and running it again. Location: ORM > Migrations > Rollbacks and recovery People use "rollback" for two different problems, and Prisma ORM deals with them differently, so work out which one you have. If the migration applied but the change it made was wrong, you want a rollback, which in Prisma ORM is one more migration. If the migration failed partway, you want recovery instead: find the cause, fix it, and run the migration again, which is safe to do. ## Rollback: a migration like any other Prisma ORM has no `migrate down` command and no "down migration" files, because undoing a change is not a special kind of operation here. To undo a change you add a new migration to your [migration history](/guides/migrations-the-migration-graph) that changes the database back to an earlier state, and it is planned and applied like every other migration. If you know git, this is `git revert` rather than `git reset`: you add something that undoes the change instead of deleting it from history. Suppose you applied `20260707T1008_add_display_name` in production and now need to undo it. Undoing it means planning a migration with [`npx prisma migration plan`](/guides/migrations-generating-a-migration), which writes the difference between the two contract states you name. A contract state is one version of your contract, the `contract.prisma` file that replaced `schema.prisma`, named by its hash. You name a state with the migration directories you already have: a directory name means the state after that migration, and `^` after the name means the state before it. To undo `add_display_name`, then, you plan from its own state back to the state before it: #### bun ```bash bunx prisma migration plan \ --from 20260707T1008_add_display_name \ --to "20260707T1008_add_display_name^" \ --name rollback_display_name ``` #### pnpm ```bash pnpm prisma migration plan \ --from 20260707T1008_add_display_name \ --to "20260707T1008_add_display_name^" \ --name rollback_display_name ``` #### yarn ```bash yarn prisma migration plan \ --from 20260707T1008_add_display_name \ --to "20260707T1008_add_display_name^" \ --name rollback_display_name ``` #### npm ```bash npx prisma migration plan \ --from 20260707T1008_add_display_name \ --to "20260707T1008_add_display_name^" \ --name rollback_display_name ``` ```text ✔ Planned 1 operation(s) migrations/app/20260707T1010_rollback_display_name └─ ⚠ Drop column "displayName" from "user" ⚠ This migration contains destructive operations that may cause data loss. from: 866ab885a8a4bd8d9f5adc47784c068be7895a7182c55cc29f9f9967d3019484 to: 967cb9f63587c1d90f64716780f04eec22b263424e89f07139233fc2c3d710c4 app space: migrations/app/20260707T1010_rollback_display_name ℹ DDL preview ALTER TABLE "public"."user" DROP COLUMN "displayName"; ``` Read the migration before you apply it, because `db migrate` runs destructive operations without asking you to confirm, and this one drops a column. Open its `migration.ts`, and run `npx prisma migration show 20260707T1010_rollback_display_name` to see its SQL. When you are happy with it, complete the rollback in this order: 1. **Save the data, if you need it.** Dropping the column deletes what was stored in it for good, so if you still need that data, copy it somewhere first. To copy it into a table that already exists, add a [`rawSql` operation](/guides/migrations-editing-a-migration#raw-sql) running an `INSERT ... SELECT` before the `dropColumn` call in `migration.ts`. Then [recompile the migration](/guides/migrations-editing-a-migration) by running `node migrations/app/20260707T1010_rollback_display_name/migration.ts` from your project root, so that your edit reaches the file `db migrate` actually runs. 2. **Revert the change in your contract.** Your contract describes the database you want, so undoing the change in the database means undoing it in the contract too: remove `displayName` from your contract file, then run `npx prisma contract emit`, the command that replaces `prisma generate` and rewrites `contract.json`. Step 4 depends on this, because `db migrate` applies migrations until the database matches the state recorded in `contract.json`. 3. **Commit the migration and the contract together.** The two only make sense as a pair, so put them in one commit: the new migration's directory, your contract file, `contract.json`, and `contract.d.ts`. No new directory appears under `migrations/snapshots/`, which is expected, because a rollback ends at a contract state that already has one. 4. **Apply the rollback.** In CI and production, run `npx prisma db migrate`, the command that replaces [`migrate deploy`](/guides/introduction-2-orm-coming-from-prisma-orm-7). In development, add [`--advance-ref db`](/guides/migrations-generating-a-migration#the-db-ref-skipping---from) so that the next `migration plan` starts from what you just applied. Once you have applied the rollback, `npx prisma db verify` passes, which confirms the database matches your reverted contract. A database that never had `add_display_name` applied needs neither that migration nor its rollback, and it runs neither, because `db migrate` runs the fewest migrations that end at the contract state you asked for. Undoing several migrations at once works the same way. Plan one migration with `npx prisma migration plan --from --to "^" --name rollback_changes`, then follow the same steps. The difference is step 2, where instead of deleting a single field you restore your whole contract file from a commit made before the oldest migration you are undoing, for example with `git checkout -- src/prisma/contract.prisma`. ### One planning caveat after a rollback The first migration you plan after a rollback prints a warning when you do not pass `--from`, even if you applied the rollback with `--advance-ref db`: ```text ⚠ The default origin ref 'db' points at 967cb9f63587c1d90f64716780f04eec22b263424e89f07139233fc2c3d710c4, which already has a migration leading to 866ab885a8a4bd8d9f5adc47784c068be7895a7182c55cc29f9f9967d3019484. Planning from it forks the migration graph; pass --from to choose the origin explicitly. ``` Without `--from`, `migration plan` starts from the `db` ref, the file in `migrations/app/refs/` naming the contract state you last applied in development. After a rollback that state already has a migration starting from it, because the rollback ends at exactly the state `add_display_name` starts from. The migration is planned anyway, and it starts from the state the rollback ended at, so you can keep it. To plan without the warning, pass `--from` with the rollback's directory name: #### bun ```bash bunx prisma migration plan --from 20260707T1010_rollback_display_name --name add_nickname ``` #### pnpm ```bash pnpm prisma migration plan --from 20260707T1010_rollback_display_name --name add_nickname ``` #### yarn ```bash yarn prisma migration plan --from 20260707T1010_rollback_display_name --name add_nickname ``` #### npm ```bash npx prisma migration plan --from 20260707T1010_rollback_display_name --name add_nickname ``` Once you apply this migration with `--advance-ref db`, the `db` ref names a state that no migration starts from, and `migration plan` no longer prints the warning. ## Recovery: when a migration fails partway When a migration fails, `db migrate` stops at the operation that failed rather than carrying on, and it tells you which operation it was and why: ```text ✘ [MIGRATION.RUNNER_FAILED] Operation alterNullability.setNotNull.user.nickname failed during precheck: ensure no NULL values in "nickname" why: Migration runner failed docs: https://docs.prisma.io/docs/orm/v8/reference/error-reference/MIGRATION.RUNNER_FAILED ``` How much a failed run leaves behind depends on your database, and [when something goes wrong](/guides/migrations-applying-a-migration#when-something-goes-wrong) explains what you are left to clean up on PostgreSQL and on MongoDB before you try again. 1. **Read which check failed.** The error tells you where the run stopped, because it names the operation and the [check](/guides/migrations-how-migrations-work#every-operation-checks-itself) that failed, and a precheck is a check that runs before its operation rather than after. In the example above, the precheck found rows with `NULL` in `nickname`, so the run stopped before setting the column to `NOT NULL`. 2. **Fix the cause, then run `npx prisma db migrate` again.** Re-running the same command is the whole of recovery, because there is no `migrate resolve` step first, and in development you add `--advance-ref db` as usual. Sometimes the cause is the environment, such as a PostgreSQL extension the server lacks or permissions it is missing. Sometimes it is the migration itself, which is why a migration can pass in development and fail in production, where the data is different. In the example above the data is what stopped the run, so you would edit the migration to [fill in `nickname` for existing rows](/guides/migrations-editing-a-migration#worked-example-making-a-column-required) before the `setNotNull`, recompile as in the rollback's step 1, and apply again. ### Drift: when the database changed without a migration Drift is what you have when your database no longer matches what your migrations say it should. The [marker](/guides/migrations-the-migration-graph#terms) is the record in the database of which contract state that database matches, and which kind of drift you have depends on whether the marker is part of the problem. In the first kind, the marker records a contract state that no migration ends at. You usually get there through [`npx prisma db update`](/guides/orm-db-update), which makes a database match your contract without a migration. The next `db migrate` fails with an error whose `code` is `MIGRATION.MARKER_MISMATCH` before it runs any operation. To fix it, write the migration your history is missing before you change the contract again: run `npx prisma migration plan --from --name `. That migration ends at the state `db update` applied, so the next `db migrate` there has nothing to run. In the second kind, only tables or columns changed, for example with a hand-run `ALTER`. The marker still records the last contract state applied, so `db migrate` still runs. It skips an operation whose change is already in the database, and it fails if an operation's check fails, or if your contract describes something missing or different once the operations have run. Before you decide what to do about drift, find out which contract state the database matches. These commands only read, and both connect to `db.connection` in `prisma.config.ts`, or to the URL you pass with `--db`: - **[`npx prisma migration status`](/guides/migration-migration-status)** shows you the contract state the marker records, labeled `@db`, which despite the name is not the `db` ref. - **[`npx prisma db verify`](/guides/orm-db-verify)** checks both the marker and the tables against your contract, and lists each difference under `Schema issues`. Pass `--schema-only` when you want it to check the tables alone. When a change was made by hand, you have to decide whether you want to keep it, and either answer gives you a way out: - **Undo it.** Change the tables back by hand until `npx prisma db verify --schema-only --strict` passes. The marker never changed, so there is nothing else you need to put right. - **Keep it.** Add the change to your contract, run `npx prisma contract emit`, then plan and apply a migration as usual. `db migrate` skips the change you already made there. [`npx prisma db sign`](/guides/orm-db-sign) fixes neither kind of drift, because it is for [baselining](/guides/migrations-the-migration-graph#baselines) a database that has no marker at all but whose tables already match your contract. For a database that Prisma ORM 7 migrated, follow [step 4 of the upgrade guide](/guides/upgrade-prisma-orm-postgresql#4-transfer-migration-ownership) instead. > \[!NOTE] > What's early > > Rolling back, the warnings about destructive operations, and re-running a failed migration all work today. What does not exist yet is a way to try a migration on a temporary copy of the database first. For anything unusual, ask on [Discord](https://pris.ly/discord). ## Prompt your coding agent Projects created with `npm create prisma@latest` include the [Prisma ORM skills](/guides/tools-skills#available-skills-for-prisma-orm-8), instruction files for your coding agent. In an existing project, run `npx prisma skills sync`. Ask your agent to: - "Plan a rollback for the last migration and show me its destructive operations." - "This db migrate run failed. Read the error, fix the migration, and re-run it." - "Check whether staging has drifted from the contract and explain the differences." ## See also - [Applying a migration](/guides/migrations-applying-a-migration): what happens when a run fails - [Editing a migration](/guides/migrations-editing-a-migration): fixing a migration that failed on data - [The migration graph](/guides/migrations-the-migration-graph): why a rollback is one more migration ## Related pages - [`Applying a migration`](/guides/migrations-applying-a-migration): The db migrate command applies the migrations you planned, until your database matches your contract, with a preview, checks on every operation, and safe re-runs. - [`Editing a migration`](/guides/migrations-editing-a-migration): A migration is TypeScript you own.
