We have a SQL 2008 installation on a Windows 2008 machine. We are planning on upgrading to SQL 2008 R2. Would the installation be in place - meaning - the upgrade will not disturb any of the services and simply upgrade or wipe out every thing and put a new instance? We have several applications (databases) on this server including Reporting Services. Some of these is very hard to recreate. What I am expecting is to run the upgrade and once finished continue to use everything as usual without missing a beat.
Thanks in advance for the response.
