New iMac has 10.11, current imac has 10.11. How best to get to 10.12?

hal,

I just cloned my mini's Sierra OS to to my "new" iMac 2015 refurb. It is one sweet machine. Added 2x8GB sticks from our sponsor.

Should I wipe the new machine, install 10.12 then migrate? Or should I migrate NOW and then upgrade to 10.12?

What do you think?
