If you're applying to do a Student Program at the Disneyland Resort in California, you would need to meet DLR Transfer Guidelines, even if you are transferring from another Business Unit (WDW, TDS, etc.) which are as follows:
No discipline notations (Coachings, Warnings, Verbal & Written Reprimands, etc.) on your SAP Record Card for a period of at least four months.
Appropriate scheduling availability.
If you are applying to do a Student Program at the Walt Disney World Resort in Florida, I do believe they'll allow you to transfer, even if you don't nominally meet Florida-Site Transfer Guidelines.
