To upgrade the server, download the installer for the desired server version and install it in the same directory path as the old server. Do not uninstall the old server before launching the installer. The latest Hansoft server can be downloaded here.
Check the server log for any problems after the installation has finished (see Logs and Email Notifications).
The Windows installer does not require you to manually stop the service when upgrading. Restarting the service is also handled automatically.
