Both Splunk Apps for Microsoft Exchange and Windows Infrastructure have overlapping saved searches. Should I use on or the other?

[BP9906]

I have both apps installed and there are many saved searches doing the same thing. Do I need to just use one or the other or are there some features missing from Exchange that are in Infrastructure?

Searches from these 2 apps are consuming most of the resources on my 3 search head cluster members. 😞

You should only need Exchange, Windows Infrastrcuture comes bundles as part of the Exchange App.
