We have a reseller in Plesk Panel, and we need to move a client from one reseller to another one. How I can do it?
Is there way to change customer's owner through GUI and CLI?
There is no way to move customers between resellers in Parallels Plesk Panel. We already have a feature request to implement such functionality, its number is #PPPM-85 for your reference.
However, for now there is no ETA when such functionality will be implemented.
