XBox One achievements question

I considering getting an Xbox One and want to know if I use my Xbox 360 profile on the Xbox One, does the gamerscore earned on xbox 360 get separated from the gamerscore earned on xbox one? I have 39,000 Gamerscore currently and want to finish off my time
on the 360 with 40,000 after I complete The Witcher 2.

Will the Xbox One Day One Achievement pop up once the update is complete?

Here's what will happen: Any mp achievements you have on the 360 will unlock on the One after you do the rank transfer and play at least 1 match so it syncs to the server. Any sp achievements you will have to re-earn by playing the campaign. From this point
on the 360 and One version will have different ranks and will not sync up. I'm rank 53 on the 360, but rank 60 on the One. If you unlock any further mp achievements, say ones associated with the dlc, on the Xbox One, and you go back to the 360 they will not
unlock. You would have to get those unlocked separately. I hope this helps.

 

Your gamerscore carries on when you move onto xbox one

 

Does it say anywhere on the dashboard how much gamerscore was earned from 360 games and how much gamerscore was earned from X1 games?

 

No it doesn't separate the score you get on 360 and on the one you can see your 360 games and what cheevos you got but I think that's about it

 

It does on the 360.If you go to your achievements on a 360 it will show all the xbox one games as just one thing so you can see how much Gamerscore you've got on the xbox one.
