Know the expiry date
Check when the current license period ends and whether renewal is automatic or requires a new payment. A reminder is not proof that renewal succeeded. Keep billing contact details current and verify renewal status after a confirmed payment.
Plan the address move
Before migrating to another server, check whether the license supports an IP change, its limits and any fee. Do not assume an IP change also changes the operating system eligibility or the package.
Keep a traceable request
Use the existing license record and include the intended new public address. If the provider does not offer a verified change operation, support should explain the restriction before any charge or cancellation is attempted.
