Hello anonymous user,
Thank you for posting here.
As I understand, we should disable /remove the folder redirection policy first, that is we should redirect back our redirected folder to the local userprofile location when the policy is removed.
Then migrate /redirect/ move Windows known folders to OneDrive.
For more information we can refer to link below.

Tip: The sequence of operations is not to migrate to Onedrive first, and then disable the folder redirection policy.
Hope the inofrmation above is helpful.
Should you have any question or concern, please feel free to let us know.
