Multiple Personal Sites

I have many users who have 2 URL's for their Onedrive.  For Example,

https://tenant-my.sharepoint.com/personal/username

and

https://tenant-my.sharepoint.com/personal/username1

The active onedrive/my Sharepoint URL is the one with username1.  How do I get rid of the original URL that was provisioned many years ago and is still there.

Thank you
