Compatibility?

I have Diablo 3 for 360. I want to get the Ultimate Evil Edition game but I have a couple questions.

1.) If I get D3:UE Edition on Xbox One, I know I can transfer my characters to it. BUT, will I still be able to play with them on the 360 from that point? Not transferring back and forth, just have two saves on each system to then start a new direction.
Reason being a buddy has original D3 on 360.

2.) If I get D3:UE Edition on 360, can I still play online with a buddy who only has original Diablo 3? Obviously the new content wouldn't work, but could we play the original game still?

Thanks..

:)

Backwards Compatibility Suggestions

Well I've only got a couple of suggestions as of now, that I wanna bring forward.

1: Timesplitters Future Perfect to bring that over to the One if possible (originally on Xbox).

2: Not many would agree but for some reason I quite enjoyed Conker live and reloaded and wished it made a return.

Both titles would be nice to see again remastered, I'm sure there are many more titles that'll make a nice addition to the growing collection of backward compatibilitys.

 

1: Your old diablo 3 "vanilla" save will still be there (nothing I tried myself, but read alot of places where ppl say the save is still there), but new stuff you get in vanilla d3 will not be effected on the UEE save

2: No and no, UEE and vanilla is 2 diffrent games, no connection more then you can trasnfer save from old to new. So there is no chance to play with each other. Raeson is more then its just new stuff, all old stuff is remade too so its not evel close to
equal. And then there is complatible issue
