Oh man, expected delivery for my PS4 Pro is tomorrow. O_O
(Amazon.ca)
To initiate the transfer, I should just be able to keep my current PS4 connected as is, and swap my Wii U HMDI and Ethernet Cable from it to the PS4 Pro, correct (both Ethernet Cables are connected to the same router)? If so, that simplifies things, as I don't need to pull out my receiver and/or trace a particular Ethernet Cable back to the modem. Afterwards, I'd of course switch out the PS4 with the PS4 Pro, and re-connect my Wii U with its original components.
Or maybe I'll just swap out my PS4 with the PS4 Pro right away, and use the current Wii U HDMI/Ethernet Cables with the PS4. Either works, I guess.
