They must be VMware specific MAC addresses in the format

I have tried installing in VMware and then converting to Hyper-V but
networking does not function.

Unfortunately I can't move forward with "not many changes". That is
not acceptable to our users, especially without notification of the
changes or training on the new
version.

We have intentionally avoiding updating because our phone users are all billable resources and some do not deal with change very well. Since we have no idea how our complex config will look on the new versions we can't come up with a training manual, etc etc. We are now running into a couple bugs (Extension Mobility and Call Parking) that are fixed in newer versions.

I initially looked at running a CallManager lab in VMware to give our admin staff a chance to try (manually change the TFTP server on their phones) the update before we rolled it out to the production server but the licensing limitations have temporarily killed that idea.
