# Migrate between Postgres databases

A CLI tool for **migrating data from one PostgreSQL database to another**.

> [!NOTE]  

> **This project is experimental.**

> 

> There may be bugs, and the API is subject to change. While we cannot provide professional support for experimental projects, we welcome your feedback.

## Usage

```sh

npx @neondatabase/pg-import@latest --silent false --accept-all false --source="pg-string" --destination="pg-string"

```

### Flags and Options

- `--source `: The connection string for the source PostgreSQL database. This is **optional**.

  - Example: `--source "postgres://user:password@localhost:5432/source_db"`

- `--destination `: The connection string for the destination PostgreSQL database. This is **optional**.

  - Example: `--destination "postgres://user:password@localhost:5432/destination_db"`

- `--silent`: Suppresses console output if set to `true`. The default value is `false`.

  - Example: `--silent true`

- `--accept-all`: Automatically accepts all prompts if set to `true`. The default value is `false`.

  - Example: `--accept-all true`

- `--backup-file-path`: Specifies the path and filename for the backup file. If not set, the default value is **dump_restore_{randomly_generated_string}.bak**.

  - Example: `--backup-file-path "../Downloads/example.bak"`

## When Migrating to Neon

- Make sure your Neon plan supports your database size. The Neon Free Tier offers 0.5 GiB of storage. For larger data sizes, upgrade to the Launch or Scale plan. See [Neon plans](https://neon.tech/docs/introduction/plans).

- If you are on the Neon Launch or Scale plan, you can optimize for the migration by configuring a larger compute size or enabling [autoscaling](https://neon.tech/docs/introduction/autoscaling) for additional CPU and RAM. See [How to size your compute](https://neon.tech/docs/manage/endpoints#how-to-size-your-compute).

- This utility uses `pg_dump` and `pg_restore`. A generated dump file containing any of the following statements will produce a warning or error when data is restored to Neon:

  - `ALTER OWNER` statements

  - `CREATE EVENT TRIGGER` statements

  - Any statement requiring the PostgreSQL superuser privilege or not held by the role running the migration

  See [Import from Postgres](https://neon.tech/docs/import/import-from-postgres) for possible workarounds.
