If there is an EA subscription within Azure with an already functional EnrollmentReader configuration within one tenant in CloudHealth and the goal is to move that enrollment to a different tenant, the platform is unable to perform that action. CloudHealth is unable to move existing enrollments between tenants.
Due to the platform being unable to move the EA between the tenants, the only option is to delete the the EA account from the existing tenant and re-create it in the new tenant. Historical data will then be collected in the new tenant once configuration is complete.
