The `kapacitord downgrade` reverts a topic store format upgrade.

Some versions of Kapacitor change the format of the topic store (for example: 1.6 to 1.7).
If you find that you need to use a previous version of Kapacitor with a different
topic store format, use this command to migrate the topic store back to the
previous format.

## Usage

```sh
kapacitord downgrade
```
