[Observium] moving observium from one machine to another

Hello,

we're using subscription version of Observium. Time has come to move the Observium from old to new mashine, do is't possible to to just copy /opt/observium from old mashine to new and make it work with all the history of graphs saved. ? Also we're using weathermap, is it possible by doing this way (just moving Observium) to save weathermap interface numbers ?

Thanks
