Hi Vern,
In generally I agree with Sandeep.
You can check in the documentation section of Empower or TechCommunity for the System Requirements Documentation.
Latest version of Broker is 9.6 as far as I know, but I have seen that there is also a version 10.5.
I am not sure if there is also a version 10.1 and/or 10.3 as I did not try to load them.
Regards,
Holger
