I just got my new CM3+, it booted on the CMIO (v3.0) board. But the display resolution is way off and nothing plugged in the USB (host) seem to work, mouse, keyboard, wifi, hub, nothing works. I did perform update and dist-upgrade on another pi first.

Which version of the CM3+? What other steps did you do to boot it?

Where to find the version? It's a CM3+ lite with all new heatsink, has a barcode with 07/12 under it and 1.12 printed on the back.

I burned the raspbian desktop (1.1G) to my SD card, put into the CMIO board together with my old CM3, did update and dist-upgrade, then replace the CM3 with CM3+, that's all.

It does help to specify CM3L and CM3L+. The other versions have on-board eMMC flash. But with the "L" models...yes, updating an SD card and booting from that should work.
