Shimano Ultegra 6800 11 Speed upgrade

Hi All
My 2017 frame is running Shimano Ultegra 6800 11 Speed at the minute.
Does this mean your stuck with using Shimano Ultegra Di2 6870?
Or
Can you drop Shimano Ultegra FC-R8000 / Shimano Ultegra Di2 R8050 on the bike?
My main concern is the rear mech. As the frame is setup for the 6800 (rear hanger wise).
As everything else seems pretty standard.
Thank you reading my post

What are you trying to accomplish?

If you have an 11-speed Shimano system right now, and don't want to change the rear derailleur, then you should stay within the Shimano or Shimano-compatible 11-speed line of components (cassettes, chains, etc.).

If you want to change to electronic shifting, then you will be changing the shifters and the derailleurs. (And, of course, removing shift cabling and re-wiring those portions of the frame.) You can stick with conventional 11-speed cassettes and chains.

R8000 and 6800 components are completely interchangeable.

As long as you stay all mechanical or all Di2, you can run them in any combination you wish.

If your bike is running 6800 then it will also run R8000. Everything mounts the same.

But it may not be well suited for DI2.

Need to check that the frame was set up for di2 but if it's a 2017 with ultegra more than likely it should be also merlincycles out of uk has the older version think it's 6800 for under 900 bucks
