How to order a new plan with a domain belonging to an existing plan
Because existing two different hosting plans with one domain is impposible in dnp control panel, (repetative domain name is forbidden) you should create your new plan with a different domain name wchich doesn't exist in dnp cp.
After creating the new plan you should make backup of all data of the existing domain in last hosting service and then when you were sure, delete this domain and next add this domain to new hosting plan.
