Co-Host to Owner transition / duplicating listing

[Alex598]

Proper way to re-list an active listing?

I am helping two friends with their listing. One set up the original listing as the Owner, the other is the co-host. The one is set up as the Owner can no longer be involved so they want to set up a new listing with the person who will be handling it going forward as the Owner. 

They do not have any guests currently booked. I want to avoid any issues with the new listing being flagged as a duplicate because I've read it can be a nightmare trying to get it unflagged/relisted. How do I do this properly?
