At present, node wallet does not support automatic upgrade, so it needs to be operated manually. The following is the upgrade method under Windows and Linux systems.
Windows
Stop running Windows node wallet (close the startup window);
Download the latest Windows package from GitHub (https://github.com/nuls-io/nuls-v2/releases), and decompress it to the specified directory (the directory path cannot contain Chinese: the Chinese path will prevent the command line from being opened);
Delete the data directory of the stopped node wallet;
Double-click start.bat with the left mouse button to start the node wallet;
Double-click cmd.bat with the left mouse button to enter the command line and view the node wallet height (network info);
When the latest height of the node wallet is consistent with the network height, it proves that the node wallet is operating normally.
Linux
Stop running node wallet (./stop);
Download the latest Linux package from GitHub (https://github.com/nuls-io/nuls-v2/releases) and unzip (tar -xvf NULS_Wallet_linux64_v2.3.0.tar.gz) to the specified directory;
Delete the data directory of the stopped node wallet;
Start node wallet (./start);
Enter the command line (./cmd) and check the node wallet height (network info);
When the latest height of the node wallet is consistent with the network height, it proves that the node wallet is operating normally.
