That is correct. You’ll surrender your AA1 license in favor of a grouped license (AA2 + AA1). If you’ll look carefully at the deposited license it contains both - AA1 and AA2.
Just keep in mind surrender requires the AA1 license is deactivated on all devices (iLok and Machine) before surrender is available.
