# Migrate from Supabase (/docs/guides/switch-to-prisma-postgres/from-supabase)

Move application data from Supabase to Prisma Postgres and reconnect your application.

Location: Guides > Switch to Prisma Postgres > Migrate from Supabase

Move your PostgreSQL application data from Supabase to Prisma Postgres with `pg_dump` and `pg_restore`, then reconnect and verify your application.

This guide works with Prisma ORM 8, Prisma ORM 7, earlier Prisma ORM versions, and standard PostgreSQL clients. Moving your database does not require changing your ORM version.

> \[!WARNING]
> What this guide does not migrate
>
> This guide migrates PostgreSQL schemas and data you own. It does not migrate Supabase Auth users and configuration, Storage objects, Realtime configuration, Edge Functions, API settings, or other Supabase platform services. Plan replacements for any services your application uses before switching it to Prisma Postgres.
>
> The final dump is a snapshot. For a production cutover, stop or drain source writes before the final dump and keep them stopped until validation succeeds and traffic switches to Prisma Postgres.

## Prerequisites

You need:

- your Supabase database password
- access to the Supabase project's **Connect** panel
- a new, empty [Prisma Postgres database](https://console.prisma.io/?utm_source=docs\&utm_medium=content\&utm_content=guides)
- the [direct and pooled Prisma Postgres connection strings](/guides/database-connecting-to-your-database)
- enough local disk space for the compressed database dump
- PostgreSQL 17 command-line tools: `pg_dump`, `pg_restore`, and `psql`

Confirm that all three tools use PostgreSQL 17:

```bash title="Terminal"
pg_dump --version
pg_restore --version
psql --version
```

Each command should report version `17.x`. PostgreSQL 17 `pg_dump` cannot dump a source server newer than version 17.

## 1. Connect directly to Supabase

In your Supabase project, click **Connect** and copy the **Direct connection** URI. Set it as an environment variable:

```bash title="Terminal"
export SOURCE_DATABASE_URL='postgresql://postgres:PASSWORD@db.PROJECT_REF.supabase.co:5432/postgres'
```

Supabase direct connections use IPv6 unless the project has the IPv4 add-on. If your network cannot reach the direct endpoint, copy the **Session pooler** URI instead:

```bash title="Terminal"
export SOURCE_DATABASE_URL='postgresql://postgres.PROJECT_REF:PASSWORD@aws-0-REGION.pooler.supabase.com:5432/postgres'
```

Use only one of these URLs. Do not use the transaction pooler on port `6543`. `pg_dump` needs session-level settings that transaction pooling does not preserve.

Check the connection, source version, and database size:

```bash title="Terminal"
psql "$SOURCE_DATABASE_URL" \
  -X \
  --set ON_ERROR_STOP=1 \
  --command="SELECT current_setting('server_version') AS server_version, pg_size_pretty(pg_database_size(current_database())) AS database_size;"
```

The command should print the server version and database size. Stop if the source is newer than PostgreSQL 17 or if you do not have enough local disk space for the dump.

## 2. Check schemas, extensions, and policies

This guide exports the `public` schema by default. List your non-system schemas to identify any additional application schemas you created:

```bash title="Terminal"
psql "$SOURCE_DATABASE_URL" \
  -X \
  --set ON_ERROR_STOP=1 \
  --command="SELECT schema_name FROM information_schema.schemata WHERE schema_name NOT IN ('information_schema') AND schema_name NOT LIKE 'pg_%' ORDER BY schema_name;" \
  --command="SELECT extname FROM pg_extension ORDER BY extname;"
```

Do not add Supabase-managed schemas such as `auth`, `storage`, `realtime`, `supabase_functions`, or `supabase_migrations` to the dump. Compare the extension list with the [extensions supported by Prisma Postgres](/guides/database-postgres-extensions). Stop and decide how to replace or remove an unsupported extension before continuing.

Inspect row-level security policies in the schemas you plan to migrate:

```bash title="Terminal"
psql "$SOURCE_DATABASE_URL" \
  -X \
  --set ON_ERROR_STOP=1 \
  --command="SELECT schemaname, tablename, policyname, roles FROM pg_policies WHERE schemaname = 'public' ORDER BY tablename, policyname;"
```

Add any other application schema names from the list above to the query filter. `pg_dump` does not copy PostgreSQL roles. Record the name of every policy that depends on Supabase roles such as `anon`, `authenticated`, or `service_role`. You will omit those policies during restore and recreate them for your new authorization design before switching the application.

## 3. Create the Prisma Postgres destination

Create a new Prisma Postgres database in [Prisma Console](https://console.prisma.io/?utm_source=docs\&utm_medium=content\&utm_content=guides):

1. Open your project and select the database.
2. Click **Connect to your database**.
3. Click **Generate new connection string**.
4. Copy both the **direct** and **pooled** connection strings.

Set the direct connection string for the import:

```bash title="Terminal"
export PRISMA_POSTGRES_DIRECT_URL='postgres://USER:PASSWORD@db.prisma.io:5432/postgres?sslmode=require'
```

Confirm that the target is reachable and empty:

```bash title="Terminal"
psql "$PRISMA_POSTGRES_DIRECT_URL" \
  -X \
  --set ON_ERROR_STOP=1 \
  --command="SELECT current_database(), current_setting('server_version');" \
  --command="SELECT schemaname, tablename FROM pg_tables WHERE schemaname NOT IN ('pg_catalog', 'information_schema') ORDER BY schemaname, tablename;"
```

The first query should report the Prisma Postgres database and PostgreSQL 17. The second query should not list any application tables.

## 4. Stop source writes and export the final snapshot

You can rehearse this process while the Supabase database remains active, but do not use a rehearsal dump for the production cutover. Before the final dump, stop or drain every application, worker, scheduled job, integration, and administrative operation that can write to the Supabase database. Confirm that writes have stopped, and keep the source frozen until step 8 switches traffic to Prisma Postgres.

If you cannot keep the Supabase database frozen for the dump, restore, and validation window, stop here. Use a separately tested migration process that durably captures and replays every post-snapshot write. This snapshot-only process does not provide a zero-downtime cutover.

Create a private, compressed archive of the `public` schema. See the [PostgreSQL 17 `pg_dump` reference](https://www.postgresql.org/docs/17/app-pgdump.html) for the other options:

```bash title="Terminal"
umask 077

pg_dump \
  --format=custom \
  --verbose \
  --no-owner \
  --no-privileges \
  --schema=public \
  --dbname="$SOURCE_DATABASE_URL" \
  --file=supabase-to-prisma-postgres.dump
```

If you identified another application-owned schema in step 2, add another `--schema=SCHEMA_NAME` option. Do not add Supabase-managed schemas.

If the application already uses Prisma ORM, also add `--schema=prisma_contract`. This copies the database marker that connects the imported schema to your existing Prisma ORM contract.

Schema-filtered dumps do not automatically include extensions. For every supported extension from step 2 except `plpgsql`, add an `--extension=EXTENSION_NAME` option. For example, add `--extension=pgcrypto` if the application uses `pgcrypto`.

`pg_dump` should finish without an error and create `supabase-to-prisma-postgres.dump`. Treat this file as sensitive because it contains your application data.

Confirm that PostgreSQL can read the archive:

```bash title="Terminal"
pg_restore --list supabase-to-prisma-postgres.dump | sed -n '1,20p'
```

You should see an archive header followed by database objects. If `pg_dump` reports a version mismatch, make sure the PostgreSQL 17 tools appear first in your `PATH`.

## 5. Restore into Prisma Postgres

Prisma Postgres already contains an empty `public` schema. Create a restore manifest that keeps that schema and restores its contents:

```bash title="Terminal"
pg_restore --list supabase-to-prisma-postgres.dump \
  | sed -E '/SCHEMA - public |COMMENT - SCHEMA public /s/^/;/' \
  > supabase-restore.list
```

The `SCHEMA - public` and `COMMENT - SCHEMA public` lines in `supabase-restore.list` should begin with `;`.

If the policy check found policies that reference Supabase-only roles, list the policy entries:

```bash title="Terminal"
grep ' POLICY ' supabase-restore.list
```

In a text editor, prefix with `;` only the `POLICY` lines for the policy names you recorded. This omits the incompatible policies without omitting their tables or data. Recreate each omitted policy with target-compatible roles after the restore and before switching the application.

Restore the remaining archive entries through the direct Prisma Postgres connection:

```bash title="Terminal"
pg_restore \
  --verbose \
  --single-transaction \
  --exit-on-error \
  --no-owner \
  --no-privileges \
  --use-list=supabase-restore.list \
  --dbname="$PRISMA_POSTGRES_DIRECT_URL" \
  supabase-to-prisma-postgres.dump
```

The command should finish with exit code `0`. The single transaction leaves the target unchanged if an error stops the restore. Errors about missing roles usually mean a row-level security policy still references a Supabase-only role; errors about extensions mean the source depends on an extension that Prisma Postgres does not provide.

Refresh PostgreSQL's query-planner statistics after the restore:

```bash title="Terminal"
psql "$PRISMA_POSTGRES_DIRECT_URL" \
  -X \
  --set ON_ERROR_STOP=1 \
  --command="ANALYZE;"
```

## 6. Verify the imported data

Create a reusable query that returns exact row counts for the migrated schemas:

```sql title="row-counts.sql"
\pset tuples_only on
\pset format unaligned

SELECT format(
  'SELECT %L || ''='' || count(*) FROM %I.%I;',
  schemaname || '.' || tablename,
  schemaname,
  tablename
)
FROM pg_tables
WHERE schemaname IN ('public', 'prisma_contract')
ORDER BY schemaname, tablename
\gexec
```

Add any other application schema names from step 2 to the `IN` list. With source writes still stopped, run the query against both databases and compare the results:

```bash title="Terminal"
psql "$SOURCE_DATABASE_URL" -X --set ON_ERROR_STOP=1 --file=row-counts.sql > source-row-counts.txt
psql "$PRISMA_POSTGRES_DIRECT_URL" -X --set ON_ERROR_STOP=1 --file=row-counts.sql > target-row-counts.txt
diff -u source-row-counts.txt target-row-counts.txt
```

`diff` should print nothing and exit with code `0`. Also rerun the extension and policy queries from step 2 against `PRISMA_POSTGRES_DIRECT_URL`. Resolve every unexpected difference while source writes remain stopped. Do not send production traffic to Prisma Postgres yet.

## 7. Connect your application

Choose the path that matches your application:

- [I already use Prisma ORM 8](#already-use-prisma-orm-8)
- [I use Prisma ORM 7 or earlier](#use-prisma-orm-7-or-earlier)
- [I do not use Prisma ORM](#do-not-use-prisma-orm)

Every path uses the two connection strings from step 3: the pooled URL for application queries and the direct URL for migrations and other CLI tools.

### Already use Prisma ORM 8

Keep your existing contract, migrations, and application code. Because you added `--schema=prisma_contract` in step 4, the imported database still carries the marker that ties it to your contract.

Set the pooled URL for runtime queries and the direct URL for Prisma CLI commands:

```bash title=".env"
DATABASE_URL="postgres://USER:PASSWORD@pooled.db.prisma.io:5432/postgres?sslmode=require"
DIRECT_URL="postgres://USER:PASSWORD@db.prisma.io:5432/postgres?sslmode=require"
```

If your `prisma.config.ts` sets `db.connection`, point it at `DIRECT_URL`.

Confirm that the imported database still matches your contract:

#### bun

```bash title="Terminal"
bunx prisma db verify --db "$DIRECT_URL"
```

#### pnpm

```bash title="Terminal"
pnpm prisma db verify --db "$DIRECT_URL"
```

#### yarn

```bash title="Terminal"
yarn prisma db verify --db "$DIRECT_URL"
```

#### npm

```bash title="Terminal"
npx prisma db verify --db "$DIRECT_URL"
```

The command exits with code `0` when the marker and schema match the contract. Exit code `4` means the database does not match. Check that the restore included the `prisma_contract` schema before you change anything else. Do not run `orm init` or `contract infer` against the new database; your existing contract already describes it.

### Use Prisma ORM 7 or earlier

Set the pooled URL for runtime queries and the direct URL for Prisma CLI commands:

```bash title=".env"
DATABASE_URL="postgres://USER:PASSWORD@pooled.db.prisma.io:5432/postgres?sslmode=require"
DIRECT_URL="postgres://USER:PASSWORD@db.prisma.io:5432/postgres?sslmode=require"
```

Prisma ORM 7 reads the CLI connection from `datasource.url` in `prisma.config.ts`. Point it at `DIRECT_URL` as shown in the [Prisma ORM 7 PostgreSQL setup](/guides/core-concepts-v7-supported-databases-postgresql). Prisma ORM 6 and earlier read `url` and `directUrl` from the `datasource` block in `schema.prisma`.

If your application did not use Prisma Accelerate, run `npx prisma generate` and continue to step 8.

#### Remove Prisma Accelerate

If your application connected through Accelerate, remove it now. Prisma Postgres connection pooling replaces the Accelerate connection pool. It does not replace Accelerate query caching, so remove the cache calls as well.

Uninstall the extension:

#### bun

```bash title="Terminal"
bun remove @prisma/extension-accelerate
```

#### pnpm

```bash title="Terminal"
pnpm remove @prisma/extension-accelerate
```

#### yarn

```bash title="Terminal"
yarn remove @prisma/extension-accelerate
```

#### npm

```bash title="Terminal"
npm uninstall @prisma/extension-accelerate
```

In your Prisma Client setup, remove the `@prisma/extension-accelerate` import, `withAccelerate()`, and `accelerateUrl`. Remove `cacheStrategy` options from queries, and remove calls to `withAccelerateInfo`, `$accelerate.invalidate`, and `$accelerate.invalidateAll`.

Undo any build settings you added for Accelerate: imports from `@prisma/client/edge`, `engineType = "client"` in the generator block, and the `--no-engine`, `--accelerate`, or `--data-proxy` flags on `prisma generate`. For Prisma ORM 7, connect through the PostgreSQL driver adapter. For Prisma ORM 6 or earlier, use Prisma Client with its bundled query engine or a driver adapter your version supports.

Accelerate reached edge runtimes over HTTP. For an edge or TCP-constrained runtime, use the [Prisma Postgres serverless driver](/guides/database-serverless-driver). For a conventional Node.js or Bun runtime, use the Prisma Postgres pooled TCP connection.

Regenerate Prisma Client:

#### bun

```bash title="Terminal"
bunx prisma generate
```

#### pnpm

```bash title="Terminal"
pnpm prisma generate
```

#### yarn

```bash title="Terminal"
yarn prisma generate
```

#### npm

```bash title="Terminal"
npx prisma generate
```

Search your project for `@prisma/extension-accelerate` and `prisma://`. Neither should appear.

### Do not use Prisma ORM

Keep your existing PostgreSQL client library. Point its runtime connection at the pooled URL, and use the direct URL for migrations, `pg_dump`, `pg_restore`, and other administrative tools:

```bash title=".env"
DATABASE_URL="postgres://USER:PASSWORD@pooled.db.prisma.io:5432/postgres?sslmode=require"
DIRECT_URL="postgres://USER:PASSWORD@db.prisma.io:5432/postgres?sslmode=require"
```

## 8. Verify and switch the application

Start the application with the new environment variables while production traffic remains paused, then run its existing test suite. At minimum, verify one read and one rolled-back or disposable write through the pooled connection.

Test every feature that previously depended on Supabase Auth, Storage, Realtime, or role-based RLS against its replacement. Only after the database comparison and application checks succeed, route production traffic to Prisma Postgres and resume writes there. Do not re-enable writes on Supabase. Keep the Supabase project available in a read-only state until the application is healthy on Prisma Postgres and the rollback window has ended.

## 9. Delete the local dump files

After you have verified the application and retained any audit evidence you need, delete the local dump and row-count files:

```bash title="Terminal"
rm supabase-to-prisma-postgres.dump supabase-restore.list row-counts.sql source-row-counts.txt target-row-counts.txt
```

## Recommended next step: adopt Prisma ORM

Your database migration is complete. Prisma ORM 8 is the current release, but upgrading is a separate application change. Follow the [incremental Prisma ORM 7 to 8 guide](/guides/upgrade-prisma-orm-postgresql) after the application is stable on Prisma Postgres.

If you want to complete both changes on the same day, deploy and verify the Prisma Postgres connection first. Upgrade Prisma ORM in a separate commit or deployment so failures have one clear cause.
