I have a few years worth of data collected by PRTG Traffic Grapher 126.96.36.1993 Freeware Edition on Windows 2003 ServerA
I have a licensed copy (500 sensors) of PRTG 9 on Windows 2008 R2 ServerB
I'd like to be able to retain all of my PRTG Traffic Grapher history and migrate this over to the PRTG 9 installation. All I've found so far is that only PRTG 7 can import PRTG Traffic Grapher data, but no further info on how I'd proceed from there.
Can I maintain this data and move it over to my 9 install via some in-between migration paths? If so, what is the process, and how can I obtain older version of PRTG.
