Using Bootcamp installed on external drive on new mac

Hi, I moved my internal bootcamp partition to an external bootcamp drive a few years back on my old Mac with Winclone. I recently updated my Mac to the 2019 16in Intel and would like to use the same bootcamp on the external drive on the updated Mac.

Anyone know how to do this or has done this before? Would the process be similar to this guide?

Yes, that is how it is still done.
