Splunk and Exchange Server 2013 log gathering

I've got a question here related to Splunk logging of Exchange Server data that I hope someone can help with. We've got several on-prem Exchange servers in a DAG that are running 2013, and some in our parent company that are on an earlier version - 2010 to be exact. Before Exchange 2013, some other roles and features were available such as CAS server and hub transport, but many of these features have been folded or changed. As a result, the Splunk monitoring utility that my company uses only works properly on our Exchange 2010 servers in our parent company's office.

I know nothing about Splunk, but apparently its looking for powershell scripts to run, but these have been moved or renamed. Corporate Security told me:  "It supports collection of data from Exchange Server 2007 and Exchange Server 2010. Exchange Server 2013 does not have this role, as it has been integrated into the Client Access and Mailbox Server roles.” Because of this fields seem to be “off”, more or less the same data is there but under new names / sourcetype. (New sourcetype=MSExchange:2013:MessageTracking).

The scripts it is looking for exist in Exchange 2010 but cannot be found by Splunk in 2013; does anyone have any insight how how to make Splunk work with Exchange 2013?
