Should I switch from the canon eos 6d to mirrorless?

Only switch if the 6D is holding you back. It still takes sharp pictures, and a new body won't fix a weak lens or poor light. The biggest reason to move is autofocus that finds and follows eyes, plus an electronic viewfinder that shows the exposure before you press the shutter. Your first camera explains why most people now start mirrorless.

Your EF lenses aren't stranded. The 6D page says EF lenses adapt to Canon's RF mount, and mirrorless mounts are shallow enough that adapting is easy. Lenses worth keeping include the Canon EF 24-105mm f/4L IS II USM for everyday use and the Canon EF 70-200mm f/2.8L IS III USM for sports and portraits.

Check the sensor sizes before you buy. A smaller APS-C body crops the frame, so your wide-angle lenses will frame tighter than they do on the 6D.
