We allow you to move your Total CMS license to a new domain for up to 12 months of purchase. After this time, the license is permanently associated with that domain/project.
You can only move your license a maximum of one time. Total CMS licenses are meant to be purchased for a single project and cannot float amoungst multiple website projects.
We are working on an automated approach to handle this. For now, feel free to shoot me a support email.
