App Transfer to New Developer Accounts

Hi all,

I am planning to transfer my apps to the new developer accounts(Google&Apple)

I will use the same RevenueCat account.

I want to know which issues I have to handle after the transfer.

1-) Can my subscribers use the premium features that I provide with their purchases?

2-) To be able to sell subscriptions again, do I need to create the credentials from the new developer accounts?

3-) Is there anything else which I need to handle before, during or after the transfer?

Thanks.
