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: 
    skale node backup .

​
Upgrade steps for the SGX server

  1. Confirm that the SGXWallet sgx_data directory and backup key are backed up.
  2. Open the SGXWallet configuration directory. 
    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. 
    docker compose down && docker compose pull && docker compose up -d

​
Upgrade steps for the node server

  1. Download node-cli v3.2.0. 
    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. 
    sha512sum /usr/local/bin/skale
    Expected checksum: 
    ccc2ae7a8694d75ed3f4cbc1d36dbfc4b55561fc41daecd30b52c97da6e122164333719b432fe246bc89f47737d743c2cf33b0f718070d4658789af817ee52d0
  3. Make node-cli executable. 
    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.

    Set NODE_VERSION to 5.0.0, and MANAGER_CONTRACTS and IMA_CONTRACTS to production: 
    NODE_VERSION=5.0.0
MANAGER_CONTRACTS=production
IMA_CONTRACTS=production
  5. Stop docker-lvmpy service. 
    systemctl stop docker-lvmpy
  6. Run the update procedure. 
    skale node update .env --yes
