Vmxnet3 network adapter change?

Hi,

Recently planned to upgrade network adapter from e1000 to vmxnet3 in windows 2008 Os.

As a action in a test machine, I modified the vmx file ethernet(n).virtualDev = "vmxnet3" then reregistered the virtual machine.

But the issue is whatever the setting (IP address, dns suffix) assigned to earlier network card everything gone, so i need to make changes again.

So is there any other way to keep the existing setting (IP address, mask, default gw, dns suffix) and change the network adapter type?

Thanks in advance.
