Will my new iMac boot off of my External bootcamp drive

I am currently using a 2014 5K iMac with an external Bootcamp drive and will soon be moving to a new iMac.
Will the new iMac boot from the external Bootcamp drive?

It should work, but it depends on the Windows drivers. If it is Windows 10, and it worked on the 2014 5K iMac, it should work fine.
