that would be simply by downloading PRTG 8 and installing it on top of your existing PRTG 7 installation.

Best Regards.

When doing this upgrade, I lost all my 600+ sensors and the associated data. PRTG only shows the default local probe device.

All I did was run the .exe on top of the old v7 version. How can I get all my sensors back?
