Connection 1 APS instance to 2 EBS Sources

Hi All

We are on below versions on source EBS and destination APS and Demantra instances

EBS Source 1 :                  11.5.10.2

EBS Source 2 :                  12.1.3

APS Destination:                12.1.3

Demantra :                          7.3.1.4

We are intending to connect our VCP instance to the above 2 EBS instances. I am aware of a patching activity to make this work.

However would like to know any other hurdles that we have to take this approach.

And since this is just for testing purpose would it be better idea to have the EBS instances connected to separate VCP instances.
