# Upgrade to v5.0.0

> SKALE node upgrade steps from 4.0.1 to 5.0.0

<Note>
  Before beginning the upgrade, create and store backups on another machine:

  * Back up the SGXWallet `sgx_data` directory and `sgx_wallet_backup_key.txt`.
  * Back up the node:

    ```bash theme={null}
    skale node backup .
    ```
</Note>

## Upgrade steps for the SGX server

<Steps>
  1. Confirm that the SGXWallet `sgx_data` directory and backup key are backed up.

  2. Open the SGXWallet configuration directory.

     ```bash theme={null}
     cd sgxwallet/run_sgx
     ```

  3. In `docker-compose.yml`, set the SGXWallet image to `skalenetwork/sgxwallet_release:1.10.2`.

  4. Pull and start the updated SGXWallet container.

     ```bash theme={null}
     docker compose down && docker compose pull && docker compose up -d
     ```
</Steps>

## Upgrade steps for the node server

<Steps>
  1. Download node-cli v3.2.0.

     ```bash theme={null}
     curl -L https://github.com/skalenetwork/node-cli/releases/download/3.2.0/skale-3.2.0-Linux-x86_64 > /usr/local/bin/skale
     ```

  2. Verify the node-cli binary checksum.

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

     Expected checksum:

     ```text theme={null}
     ccc2ae7a8694d75ed3f4cbc1d36dbfc4b55561fc41daecd30b52c97da6e122164333719b432fe246bc89f47737d743c2cf33b0f718070d4658789af817ee52d0
     ```

  3. Make node-cli executable.

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

  4. Update `.env` option names and values.

     Replace each legacy option with its new option; do not keep both names in `.env`.

     | Legacy option               | New option             |
     | --------------------------- | ---------------------- |
     | `DISK_MOUNTPOINT`           | `BLOCK_DEVICE`         |
     | `DOCKER_LVMPY_STREAM`       | `DOCKER_LVMPY_VERSION` |
     | `CONTAINER_CONFIGS_STREAM`  | `NODE_VERSION`         |
     | `MANAGER_CONTRACTS_ABI_URL` | `MANAGER_CONTRACTS`    |
     | `IMA_CONTRACTS_ABI_URL`     | `IMA_CONTRACTS`        |
     | `SGX_SERVER_URL`            | `SGX_URL`              |

     Set `NODE_VERSION` to `5.0.0`, and `MANAGER_CONTRACTS` and `IMA_CONTRACTS` to `production`:

     ```bash theme={null}
     NODE_VERSION=5.0.0
     MANAGER_CONTRACTS=production
     IMA_CONTRACTS=production
     ```

  5. Stop docker-lvmpy service.

     ```bash theme={null}
     systemctl stop docker-lvmpy
     ```

  6. Run the update procedure.

     ```bash theme={null}
     skale node update .env --yes
     ```
