Hi Ray,

the answer to all your questions is Yes.

If you are planning to do this without remote access you
will need to be careful that you don't loose network connectivity
- e.g. due to a misconfiguration while setting things up.
For this reason I would suggest using at least one of the
following if possibile.

1) A separate physical NIC for admin
2) Serial console or other lights-out access

If that is not possible you will just need to be super careful.
I would start with a trial run on machines you do have console
access to.
