Hello,
I have 2 sandbox tenants, one of them is old and the other is new. I would like to copy or transfer all the data from the old tenants to new tenant along with the collaborative space and the bookmarks, is this possible, if so can anyone share the documentation of the processes. 
Edit: I am aware of the exchange management, in there I have used Utility command - Batch Monitor - Global Export from Collaborative space. But in this I get the CAD data but not the Bookmark structure along with it. 
 

Thank you.
