So, after converting physical machine, can I use the physical machine? OS and data will present on the physical box? or it will vanish out?
Pleae advice as I am new to this converter.
Yes, the VMware Converter will not do anything to the existing server except make "clone", if you will, of the physical server. The physical server will remain the same and all data will still be present. Keep in mind, if you want to keep the physical server on-line, you should think about changing the HOST name of the VM as well as the IP address.
After P>V migrations we usually leave the physical box powered off for a couple of weeks just to ensure everything is fine on the VM. Once that period has passed we decommission the physical server.
