You can save the PowerChute EventLog, Datalog from the old system. Do a clean install of PowerChute on the new system. Stop the PowerChute service on the new system. Then replace the newly created EventLog and Datalog files with the old system and restart the PowerChute service. The new system will now display the historical Event and Data logs.
As for the configuration, that will have to be replicated manually.
Another option if you are running PowerChute Agent version 10 is to go to About, and at the bottom of the page, you can create an archive.zip. This will save your data to a zip. You can then uncompress the file and view the historical event, data, and energy usage logs with a text editor.
