change subscriber to domain names already created

[Pecnet]

Hello,

I would like to know if you can change a subscription for a domain.

At first I have a plesk admin web account, and have migrated to a Plesk web pro version.

I have a subscribers with 3 domain names, and I would be separated and assigned to another subscriber.

what is the problem can create a subscriber with a new domain.

So like I said I would like to create a new subscriber with a domain name already created

Thank you
