We currently have SSRS 2005 and will be migrating to SSRS 2008 (not R2) very soon.
Most of our applications are VS2005 ASP.NET Web applications. We do not have any plans to upgrade the applications in the near future. The applications use different methodologies to access the SSRS reports.
Some use the URL Access method - build a url with all parameter data (and PDF rendering extension) and open the url.
Some use a report viewer control working in the Server mode (Remote mode) to display the server reports.
Some use the ReportingService2005.asmx web service to render reports as pdf/excel
How the clients could be impacted in each of these scenarios, if we just upgrade the SSRS from 2005 to 2008?
