Is there any way to merge two maps from two different dude servers?
Thanks

A device could be copy/pasted within one map. Try to open 2 copies of dude client (connected to different servers) and copy devices from one map to another.

This will not transfer the relations and recorded historical data.

But that's the way to solve a problem.

What solves copying the blank box? Without transferring of the recorded historical data it is useless.
