Hello, we appreciate your contact.

We can't confirm the effects of an in-place upgrade from Windows 2003 to 2012 on the system which runs PRTG. To "play safe" you should move PRTG's data to a different system and perform a clean install of the server, afterwards you may restore PRTG's data and re-install the latest stable version.

You may even move PRTG to a different system (using a trial key/freeware version) and run it there for up to 30 days without issues.

Please check our official migration guide:
