Hey Alberto,
Yes, the server has an automatic update feature which will automatically apply database migrations and replace files to the latest version. As a rule of thumb, it's always a good idea to backup the pcmonitor database and the c:\hosting folder just in case something goes wrong, even though the automatic update system has built-in failsafe procedures. You can watch the self update process by looking at the most recent c:\logs\ServerUpdate_*.log file. Make sure that the Pulseway Enterprise Server Update service is running and can connect to our cloud services.
Let me know how it goes!
