You can check this link how to ask for removal of IPP protection.
In email, write your registered email id.
In Destination Activation Code, provide destination active code from Administration tab (Service center) of your licensed environment.Upload an eSpace which you want to convert from personal to other.
You'll receive an email with the espace which you can use in other environment whose Activation code you had sent.
(Alternatively you can ask to link your personal environmnet with your licensed environment.)
Hope this helps.
Thanks and Regards,
