> SKALE node upgrade steps from 3.0.3 to 3.1.0

## Upgrade steps from 3.0.3 to 3.1.0

<Steps>
  1. Download new node-cli binary

     ```bash theme={null}
     curl -L https://github.com/skalenetwork/node-cli/releases/download/2.5.0/skale-2.5.0-Linux-x86_64 > /usr/local/bin/skale
     ```

  2. Verify checksum using sha512sum command

     ```bash theme={null}
     sha512sum /usr/local/bin/skale
     ```

     Expected checksum

     ```bash theme={null}
     2a409323eae26b14e4c5c018ae0b164da81a67793bcc1fcb96a266afab4e8672c587f1a6c4fd2e4c1d8ee1644616efc2e28249549108c0711c9cdce59b9047a8
     ```

  3. Make node-cli executable

     ```bash theme={null}
     chmod +x /usr/local/bin/skale
     ```

  4. Update the following parameters to the new values

     ```bash theme={null}
     CONTAINER_CONFIGS_STREAM=3.1.0
     ```

  5. Execute update

       <Note>
         From 3.1.0 it will not be possible to run upgrade while critical network operation is in progress.

         But before changes are made --unsafe option is required to run upgrade.
       </Note>

     ```bash theme={null}
     skale node update .env --yes --unsafe
     ```
</Steps>
