Yes, but depending on previous history, you may have to open a ticket to get another reset.
I recommend that you first test without Class of Service to confirm that everything else is working properly.
Like @Stewart1 yes but there is a limited amount of times you can move activation between different hardware before you need to reach out to customer support to grant you additional activation.
I’ve done it before and it doesn’t take long for them to do it but the system is in place to discourage you from doing this too often.
