It's required whenever we introduce breaking changes to the json snapshots of the schema and upgrade the internal version.

`drizzle-kit up` command requires you to specify both `dialect` and database connection credentials, you can provide them either via [drizzle.config.ts](/docs/drizzle-config-file) config file or via CLI options

```ts {5,8} // drizzle.config.ts import { defineConfig } from "drizzle-kit"; export default defineConfig({ dialect: "postgresql", }); ``` ```shell npx drizzle-kit up ```

```shell npx drizzle-kit up --dialect=postgresql ``` ### Multiple configuration files in one project You can have multiple config files in the project, it's very useful when you have multiple database stages or multiple databases on the same project: drizzle-kit migrate --config=drizzle-dev.config.ts drizzle-kit migrate --config=drizzle-prod.config.ts ```plaintext {5-6} 📦 ├ 📂 drizzle ├ 📂 src ├ 📜 .env ├ 📜 drizzle-dev.config.ts ├ 📜 drizzle-prod.config.ts ├ 📜 package.json └ 📜 tsconfig.json ``` ### Extended list of configurations We recommend configuring `drizzle-kit` through [drizzle.config.ts](/docs/drizzle-config-file) file, yet you can provide all configuration options through CLI if necessary, e.g. in CI/CD pipelines, etc. | | | | | :-------- | :--------- | :---------------------------------------------------------------------- | | `dialect` | `required` | Database dialect you are using. Can be `postgresql`,`mysql` or `sqlite` | | `out` | | Migrations folder, default=`./drizzle` | | `config` | | Configuration file path, default=`drizzle.config.ts` |
