What does DHCP had to do with the BDC for the purpose of upgrade?

Use a manual address for the temporary BDC's IP address.

Right, and the PDC must be online and reachable at the time of the
BDC install.

No, since the wanna-be-BDC must contact the PDC (on the net) to become
a BDC. You must use a manual address in this case.

Normally a ?DC should not use a DHCP assigned address on it's main NIC
anyway.

Use a manual address. Nothing to it.
