Using Node Binary

Validator Nodes
1. Backup Files
Create a folder called "backup" in case it does not exist:
mkdir -p backup
Backup the harmony binary file:
cp harmony backup
2. Download Node Binary
Before we proceed to next steps we need to download the node binary first:
Mainnet
Testnet
curl -LO https://harmony.one/binary && mv binary harmony && chmod +x harmony
curl -LO https://harmony.one/binary_testnet && mv binary_testnet harmony && chmod +x harmony
Check the node binary version that was downloaded:
./harmony -V
3. Restart Systemd Service
sudo service harmony restart
To check your node follow instructions on Checking A Node.
Non-Validating/Explorer Nodes
Requirements for Explorer Nodes have changed. Check here before going forward.
1. Download New Explorer DB
wget https://s3.us-west-1.amazonaws.com/pub.harmony.one/mainnet.archival/harmony_storage_db_0/explorer_storage_s0.tar.gz
2. Backup Files
mkdir -p backup
cp harmony backup
3. Download Node Binary and Stop Service
curl -LO https://harmony.one/binary && mv binary harmony && chmod +x harmony
sudo service harmony stop
4. Backup Old Explorer DB
mv explorer_storage_0.0.0.0_9000 explorer_storage_0.0.0.0_9000.backup
5. Extract New DB
tar xvzf explorer_storage_s0.tar.gz
6. Change RPC Rate Limit
Change harmony.conf file and add make sure the RPC Rate Limit is set to at least 50000:
[RPCOpt]
  RequestsPerSecond = 50000
7. Start Systemd Service
sudo service harmony start
DB migration should take no more than a few hours to conclude.
