Migrating from App store notifications server v1 to v2

Our team is migrating from Apple Server Notifications V1 to V2. We have two primary questions regarding notification delivery during this transition:

Is it possible to configure Apple to send V1 notifications to an existing V1 endpoint URL and V2 notifications to a separate V2 endpoint URL concurrently?

If concurrent delivery to distinct URLs is not supported, what is the expected behavior for outstanding/pending V1 notifications when the notification endpoint URL is updated to the V2 URL? Are V1 notifications re-sent to the new V2 URL, or are they dropped?
