Migrating to a new device

Hello I am new here, but I am using authpass for about 5 years now without issues.
Main issue: I have bought a new device and would like to migrate my passwords to the new one, both with authpass.
sub issue 1: authpass I unlock it with biometrics. If I do not find my old master password, can I create a non locked migration file or can I give a new password to the migration file, once I have the app open and unlocked (I can see hence the passwords, so either I copy by hand one on one, ore I can create a sensible file for local migration. I do not want cloud, I do not want to send it over the internet, just with bt from device to device. Is this possible?
sub issue 2: my version installed is f-droid. I see the version of google playstore is different. Do you still support the f-droid store or should I install the playstore version on the new device. You do not mention f-droid on these pages as far as I can see. Version installed from f-droid is 1.9.10+164
sub issue 3: if I need the password is there a way to recover it, since it must be somewhere given the biometric allows me to open (fingerprint) the app. Either I can change the master password to a new one and then export the migration file or you will tell me whatever procedure to follow.
Thank you for your patience.
