When updating, always have your seed at hand to be able to recover your funds in case of any problem.

While a crash is very unlikely, users renting or hosting might want to backup the folders “host”, “renter” and “wallet” as a security measure before the update. In Windows, they are located in the %AppData% folder (/Users/your_user/AppData/Roaming/Sia-UI/Sia). See Transferring the Client to a Different Computer for additional backup and recovery information.

Client update can be performed in several ways:

• A) Download the latest version of the client from http://sia.tech/apps/
• B) Close the UI completely (In Windows, click “close” on the system tray icon)
• C) Install the new version overwriting the old installation folder
• D) Open the UI again. After certain version updates, the client may need several minutes to fully initialize (for instance, from 1.2 to 1.3 it might need up to 10 minutes to accomplish the step 2/6)

Simply use the command “siac update”
