CUCM VM Network Adapter: VMXNET3 or Flexible

I just upgraded my CUCM server from 10.5 to 11 and as part of that I ran through the process to switch the network adapter to VMXNET3 as defined in the release notes. using the following commands.

1.copy CUCMServer.vmx temp_file.vmx
2.findstr /V /R "^ethernet0.virtualDev.*" temp_file.vmx > CUCMServer.vmx
3.echo ethernet0.virtualDev = "vmxnet3" >> CUCMServer.vmx

Before the change my network adapter was set to "flexible" and I still see flexible as the Adapter Type even though the line ethernet0.virtualDev = "vmxnet3" is now present in the running .vmx file

The process for changing the adapter type in IM&P was to:

1. Copy the current MAC address
2. Delete the Network adapter
3. Add the new adapter with vmxnet3 as the type
4. Manually update the MAC with the old MAC address

When I look at the VM setting for the IM&P server I do see the adapter type as VMXNET3.

Am I missing something with the CUCM servers and will the flexible type cause me problems at some point in the future?

thanks
