# panguard upgrade

> Update the Panguard CLI to the latest version.

The `upgrade` command checks for and installs the latest version of the Panguard CLI. It handles binary replacement, database migrations, and post-upgrade verification automatically.

## Usage

```bash theme={null}
panguard upgrade
```

## What It Does

1. **Checks the current version** against the latest release
2. **Downloads the new binary** from the official release channel
3. **Verifies the checksum** to ensure integrity
4. **Replaces the binary** in place
5. **Runs migrations** if any data format changes are required
6. **Verifies the upgrade** by running a quick self-test

## Examples
