Plugin move from one to another domain

Hello, why is everything so complicated? Why can’t I just disconnect the plugin from one domain, and connect it to another? Without asking for your help.
Else, I can’t understand, in order to re-connect the plugin, do I need to renew your support?
If so, the price of your plugins is already expensive enough to impose the renewal of your support. Give us the ability to re-connect the plugins ourselves inside our personal account.
