How should I go about building an effective wirking relationship with a direct who doesnt want to be "managed"?

I am just about to take on the role of managing a newly formed team (two existing teams brought together). I've been warned that one of the team members is very sensitive about her position within the new structure (sees it as a demotion as she is now a layer further removed from the GM). She also considers herself an expert in her field and is quick to tell everyone how many years experience she has. She likes to be autonomous and my perception is that she would consider any attempts at conversations around her career aspirations, development opportunities etc would make her defensive.

Any advice?
Any podcasts related to this that you can point me to?
