Aegis will let you import qr codes. You can group export accounts from Google authenticator and it will display a QR code, you will need to take pictures of the qr codes the Google authenticator provides as the app will not let you screenshot. So to do this you will need a 2nd device (like a tablet, 2nd phone, computer with a webcam). You can then scan the qr code with Aegis and it will bulk import accounts.

The problem I had was if you bulk to many accounts in an export from Google authenticator aegis will not be able to read the aqar code, so I only exported 6 accounts at a time. Still went pretty fast. Just make sure you delete the pics after you use them to import.
