I have a multisite installation using GEO Theme Child Theme

I wish to create a new site and import all the information from the existing site except the Places (although I could delete those after the event).

Basically, same site design to be created. Al that will change is the main location and places within that location.

Tried using Tools – > Import but that failed.

Please advise the best way of doing this as there may be several hundred to do.
