We can do that for you at the cost of 2,000 Realm Gold, which is equivalent to two name changes. Keep in mind that if you want to do this without contacting us, it will cost you 3,000 Realm Gold, as you will have to do a total of three name changes to successfully swap the names of the accounts yourself.
Here's the procedure:
1. We verify your ownership of both accounts
2. You purchase 2,000 Realm Gold
3. We remove the Realm Gold and swap the names of your two accounts
Feel free to contact us and we will help you out.
