Please feel free to inform me what I maybe missing or need to do, I have a Server-A(2008 R2) which we current pull our SSRS reports from. I have a three tier SharePoint Farm (2013) which has a backend DB SQL 2014 and the 2014 RS Add-in for SharePoint. I still want the reports to pull the data from Server-A but I would like the Reports to be in SharePoint. So my question is when setting up my "Application pool name" point the "Database server:" to Server-A & the "Database Name:" to my "ReportServer" database on Server-A.
