What information carries over between Bookings when Cloning?
Answer:
When you clone a Booking (Steps to do so, outlined here)
You will be presented with a list of options to copy over. The list includes: Contacts, Custom Fields, Events and Groups.
A conflict check is completed on the Events and a notification will appear if there are any conflicts.
At this point in time no other items can be brought over in a Booking.
The new Booking will follow the same date pattern as the original. So for example, if you clone a Booking with an Event, and the Event starts two days after the Booking Start Date. The same will be true for the clone.
