We are in the process of upgrading our domain environment from Windows 200, to Windows 2008 R2 (sigh of relief). When the upgrade is completed, we would like to move to using GPO software deployment.
The question I has is regarding how to manage moving hundreds of machines that have all had software manually installed, into GPO deployment. Will the software try and re-install? Will the client extension detect that they software is installed, and not attempt to re-install?
