I have a question. We are in the process of upgrading from SSRS 2005. The new servers are built with SS 2008 R2. However, my workstation only has SS 2008 R1 on it. Do I need to upgrade my local version as well? We are going to go ahead and update my reporting team's local machines to R2, but I'm wondering if this will be an issue if other developers who haven't upgraded try to work on reports for some reason. We realized this might be an issue because when we tried to make a change and redeploy a report to the new server, it stopped working correctly. I assume this is the reason for the problem.
