Uno + seeedstudio CAN shield to Nano + compact CAN shield

Currently have a project that utilizes an Arduino Uno with a Seeedstudio v1.2 CAN bus shield. For a smaller size and the ability to make more permanent connections, I want to convert to an Arduino Nano + compact Grove CAN shield (here).

From what I can tell the Uno -> Nano will work with the same code, same libraries, etc.

My concern is if the Compact Grove CAN Shield will work with the same libraries and code as my current Seeedstudio v1.2 CAN-bus shield.

Has anyone done something similar? What was the outcome?

Nevermind, it looks like the compact board uses softwareserial. Want SPI.
