There’s some guidance circulating about upgrading to 2010 with a mix of In-Place and Database Attach upgrade methods.
My Central Admin and SharePoint Web App are on a 64 bit server, but it’s running on Windows server 2003 x64 and
not on Windows Server 2008 or 2008 R2. SharePoint Team Blog says Server 2008 or 2008 R2 is required for SP2010.
If I want to do the hybrid upgrade approach, is it possible to first upgrade the OS to Server 2008 R2 on the server where my Central Admin and SP Web App runs? Or will this break MOSS 2007?
Hi Mike Erter, What is the version of your MOSS 2007? Starting from Service Pack 2, SharePoint server 2007 support windows Server 2008 R2 and Windows Server 2008 SP2. It is risky to upgrade Windows serve 2003 to Window server 2008, which may cause to SharePoint server 2007 stops work. We suggest that you choose database attach upgrade
