We are moving to a scale out deployment of SSRS 2008 Enterprise with reporting services running on 2 front ends connecting to the "ReportServer" and "ReportServerTempDB" databases on a separate SQL Server 2008 cluster.
Can you run Reporting Services 2008 R2 while connected to the report server databases that live on a SQL Server 2008 (non R2) database server?
Thanks, Dan
Yes.
Both SQL Server 2008 R2 and SDQL Server 2008 SSRS can run on a SQL Server 2005 or higher back end.
