I was not happy the default procedure to change phones was a complete reset. I found this:
In summary:
- Enable developer mode
- Enable ADB Debugging via wifi
- Find the IP address
IP="192.168.0.15:5555"
adb connect ${IP}
adb shell "pm clear com.google.android.gms && reboot"
adb connect ${IP}
adb shell am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE
The connect via the WearOS app on the new phone.
