I’m not sure what you mean, but a vna file is a text file, so you can open it in any editor to see what the parameters and to change data. However, if by parameters you mean visual properties like the color of a tie, these are set separately for every node and for every tie (see the vna file below and you will see what I mean). So I don’t think it would be practical to swap data.
