Account Transferring and Retain Proxy

Hi, I have two servers and when I transfer a cPanel account between that servers, source server cpanel will be suspended. After I can see this proxy serving thing there. Select this checkbox to keep the account"s current service proxying settings. If you do not select this checkbox, the system will disable service proxying by default.
I want to keep proxy and terminate that cPanel by clicking on that tic mark. But after three or four days, I will be wanted to remove that proxy details from the server. How can I find that proxy-related record and clean it after few days?
