Integrate two SD+ instance

Integrate two SD+ instance

Hi,
 
Due to M&A activity, we have a requirement to integrate two SD+ instances in one. The user authentication is done using AD as backend. The two AD forests and domain are now integrated and users of both SD+ are now using same AD domain.
I would appreciate any help to know:-
 
1. Is this possible to integrate both instance?
2. Is it possible to import data from one instance to another by assigning a new Request ID (since request id's overlap in both the instances)
 
If any of above is possible how this can be achieved?
 
Thanks
A. Sharma
