Move to AAB

I have several apps on Play Store using APK and the same keystore for all of them.

How do I replace them with AAB?

Just build them with newer version code and upload the .aab file?
Could this cause any problems because all of them share the same keystore?

I don’t know about the same keystore for several apps but getting builds with the newer versions and uploading the aab file should do the trick.

Just compile aab and upload it directly, just like apk.

Just like pickerel said. I do the same in the past.

I will do it, thank you!!
