You can use the “Pre-delegated zone check” on https://zonemaster.iis.se (or any other public zonemaster installation) to check your new auth (possibly on a different IP for testing purposes).
To some degree it sounds you’re not absolutely sure that all your recursive traffic is indeed sent to your PowerDNS Recursors. I’d suggest running tcpdump on your existing PowerDNS Authoritative Servers to verify that they only receive traffic from Recursors, and not from your internal devices.
