# fly mpg fork

Fork a Managed Postgres cluster into a new cluster from the source's current
data, leaving the source cluster unchanged. The fork is provisioned
asynchronously in the same organization and billed separately.

The fork uses the source cluster's plan unless --plan picks a different one,
including a smaller one.

## Usage

```
fly mpg fork [CLUSTER_ID] [flags]
```

## Options

```
  -h, --help          help for fork
  -n, --name string   The name of the forked cluster (defaults to <source-name>-fork)
      --plan string   The plan for the forked cluster: Basic, Starter, Launch, Scale, Performance (defaults to the source cluster's plan)
```

## Global Options

```
  -t, --access-token string   Fly API Access Token
      --debug                 Print additional logs and traces
      --verbose               Verbose output
```
