config :pleroma, configurable_from_database: false
```
To delete transferred settings from database optional flag `-d` can be used. `<env>` is `prod` by default.
Options:
- `<path>` - where to save migrated config. E.g. `--path=/tmp`. If file saved into non standart folder, you must manually copy file into directory where Pleroma can read it. For OTP install path will be `PLEROMA_CONFIG_PATH` or `/etc/pleroma`. For installation from source - `config` directory in the pleroma folder.
- `<env>` - environment, for which is migrated config. By default is `prod`.
- To delete transferred settings from database optional flag `-d` can be used
=== "OTP"
```sh
./bin/pleroma_ctl config migrate_from_db [--env=<env>] [-d]
./bin/pleroma_ctl config migrate_from_db [--env=<env>] [-d] [--path=<path>]
```
=== "From Source"
```sh
mix pleroma.config migrate_from_db [--env=<env>] [-d]
mix pleroma.config migrate_from_db [--env=<env>] [-d] [--path=<path>]
```
## Dump all of the config settings defined in the database
