For a flight arriving in T1 gates, you would have to T1 terminal, then go to T2 terminal and take the APM there to T2 Concourse. Maybe there is an airside walk between the two terminals that avoid immigration. That is a rather long way. Or you need to take the T1 APM to the T2 APM exchange.
Again this is all speculation, as we are talking 2025.
The current APM system:
Skypier <-> old T2 <-> T1 east <->T1 west <->T1 midfield concourse
The old T2 station will be re-designed as an interchange station to transit to new T2 - T2 concourse APM.
