App transfer account and api key issues

Question

I have an app on GooglePlay using google map api v1 and I would like to transfer my app to another account.

Here is the problem : google no longer generates keys for apimapv1 and as mentioned in google's documentation, "each Google Maps Android API v1 Key is uniquely associated with a specific signing certificate.".

If the transfer occurs, will our signing certificate (keystore files) still be valid on the new account, and will it allow the new account to use the current MapKey API v1 ?

Switching to APIMAPv2 is not an option for the moment.

I assume you mean to another developer account? Just in case you don't know how to do this properly see this answer.

The reason they are associated is simple: Google doesn't want new apps to use the old API. They do not give out new API keys so only the apps that still have an API key can use the old API. If you transfer your app, it is essentially as if you upload a new app. You would need a new API key and since you can't get one you run into a problem.

I think at this point I should mention that that is a good thing. I know that it might not be an option to upgrade to the new API, but the old API is pretty old by now, nobody should be using it any more. The new API is new for a reason after all.

However you might be able to get Google to give you a new API key, just describe your problem in the transfer form and that you need an API key for the old API. That's your best option I think, and it most likely is the only thing you can do anyway.

If the transfer occurs, will our signing certificate (keystore files) still be valid on the new account, and will it allow the new account to use the current MapKey API v1 ?

The keys are associated with the signing certificate as noted here. Your only option is to describe your situation to Google and hope that they will give you a new one or at least transfer the old one along with the app.
