I have a Windows Server 2003 R2 installed on a physical server. For the first time, we want to virtualize this server. My question is about the installation part. I have the .iso CD. Do I simply pop it in, restart the server, and boot from the CD and proceed with the install? Will this wipe the Windows Server 2003 R2 Operating System, or do I need to wipe it first before installing ESXi?
