We had a customer in plesk, which created a few websites for their customers. We created an abonnement for each of their users.
Now they grow and doubled their customers and are still growing.
So we converted their customer to a reseller.

They can create domains, abonnements on their own. But the old abonnements are connectect to the reseller.
To clean up we want to connect these abonnements to customers not existing yet.

There is a description how to move (additonal) domains ( https://www.plesk.com/kb/support/how-to-move-a-domain-between-subscriptions-in-plesk/ ).
But there are also these sentences:
“This is only possible if there are no additional domains on the subscription from which the main domain is moved. The original subscription will be removed, since it will have no domains/subdomains left in it.”.
This shows to problems if I understand it correctly:

• It is not possible to move all domains to customers, because the subscription will be deleted
• The move is not allowed, because there are other additonal domains

I have no playground to try what happens… So… It would be cool to get some help here.
