I have questions about my account transfering from xbox 360 to xbox1

I want to finally buy the handsome collection for the xbox 1, but im worried about whether the 194 things in my inventory will transfer as well. If any one has answers for me please respond

Yes they do. My character has like 300 items and they all transferred.

after transferring 60 toons from BL 2 and 30from TPS and then cking them I can confirm that all gear transferred over.
