Canon 7D Mk II to Full Frame Mirrorless

[bawrites]

I'm thinking about making the jump from a Canon 7D Mark II to a full frame Canon Mirrorless body. 

I have a number of lenses - some of which are full frame compatible. 

My question is around body compatibility.  Is there an adapter for the mirrorless camera body (full frame) that would allow non-mirroless specific Canon DSLR compatible lenses to operate. 

If you have it, and have gone down this road, what's your experience been?

I have 2 lenses in particular that are staples to me - one is a Sigma 150-600mm Contemporary and the other is a Sigma 100mm Macro lens (both fairly new/recent).

Any feedback is useful and appreciated.

The Canon built EF - RF adpaters work fine - there is no glass and some have a control ring.

When you put an EF-S lens on an R body, the camera will limt you to an APS-C sized area of the sensor.
