Regarding Changing ownership

Hi Team,


I have a query. Suppose I have a laptop with DID "did:laptp:12345"  and I
sold it to someone. Now ownership changed to my friend.
In this situation, so the did document will get updated showing the current
owner.

My concern is regarding the public and private key of the previous owner.
Will we be rotating keys at the time of such kind of processes or we have
any other good implementation .

and the previous key will go under revoke section, right?

Regards
