Change Account User via CSV Upload

[ram81]

I am trying to change the user association or assign a user for a large number of accounts associated with an endpoint via CSV. 

What is the proper attribute in the Upload Preview to select and which user attribute does it look for? 

I have uploaded the accounts to be updated via CSV and specified the username and the systemusername but the accounts Username has not been updated. 

Screenshots attached.

@ram81 : did you enable below two settings?

This partially resolved the issue. Also the username has to be the first column in the CSV.
