Prepare the transfer record
Export the current balance and recent activation history through the panel's approved route. Note the time, currency, credit unit and owner. Confirm who can respond to account recovery and who handles customer disputes. Where possible, give each person only the rights needed for their task.
Test a small change
Use a controlled training account, issue a reversible change where supported and record who did it. Confirm old access is revoked and that the new operator can retrieve evidence without relying on someone else's session. Keep credentials out of handover documents.
