How to update SSRS from 2.2.0 to 3.1.10729

Jan 2, 2013 at 4:33 PM

I've been using version 2.2.0 for about a year now and it works very well.  I just noticed the latest version is now 3.1.10729.

How do you update to the latest version?  Anything special to know?  Will it affect existing reports in any way?

I'm running SQL Server 2008 R2 SP1 on Windows 2003 SP2 x64.
