You can convert systems manually if you want to specify values other than the default values for the resultant virtual machine's properties.

The option to convert systems manually is available only if the vCenter Converter client plug-in is installed and enabled on your vSphere Client. You can verify whether vCenter Converter client is installed and enabled through the Plug-in Manager.


In the Analysis tab, right-click on a system and select Convert to Virtual Machine > Manually.


Complete the wizard to manually specify virtual machine properties.
