Upgrade storage node from v2 to v3 testnet (galileo)

Stop the node

sudo systemctl stop zgs

Backup config.toml

cp $HOME/0g-storage-node/run/config.toml $HOME/zgs-config.toml.backup

Set new contract vars

export ZGS_LOG_DIR="$HOME/0g-storage-node/run/log"
export ZGS_LOG_CONFIG_FILE="$HOME/0g-storage-node/run/log_config"
export LOG_CONTRACT_ADDRESS="0x56A565685C9992BF5ACafb940ff68922980DBBC5"
export MINE_CONTRACT="0xB87E0e5657C25b4e132CB6c34134C0cB8A962AD6"
export REWARD_CONTRACT="0x233B2768332e4Bae542824c93cc5c8ad5d44517E"
export ZGS_LOG_SYNC_BLOCK=1

Edit your config

sed -i '
s|^log_sync_start_block_number = .*|log_sync_start_block_number = '"$ZGS_LOG_SYNC_BLOCK"'|g
s|^log_config_file = .*|log_config_file = "'"$ZGS_LOG_CONFIG_FILE"'"|g
s|^log_directory = .*|log_directory = "'"$ZGS_LOG_DIR"'"|g
s|^mine_contract_address = .*|mine_contract_address = "'"$MINE_CONTRACT"'"|g
s|^log_contract_address = .*|log_contract_address = "'"$LOG_CONTRACT_ADDRESS"'"|g

Delete old database

sudo rm -rf $HOME/0g-storage-node/run/db/

Restart storage node

sudo systemctl restart zgs

Check logs

tail -f ~/0g-storage-node/run/log/zgs.log.$(TZ=UTC date +%Y-%m-%d)

Check sync status

while true; do 
    response=$(curl -s -X POST http://localhost:5678 -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"zgs_getStatus","params":[],"id":1}')
    logSyncHeight=$(echo $response | jq '.result.logSyncHeight')
    connectedPeers=$(echo $response | jq '.result.connectedPeers')
    echo -e "logSyncHeight: \033[32m$logSyncHeight\033[0m, connectedPeers: \033[34m$connectedPeers\033[0m"
    sleep 5; 
done
