DNS Express authoritative servers do not update zone information when you change the authoritative server for that zone until the next successful zone transfer from the new server.
Data from the original server is still served until the next successful zone transfer from the new server or the zone expires.
Create a DNS Express zone and provide an authoritative DNS Express server for that zone, wait for zone transfer to occur, and then change the authoritative server.
Delete and recreate the DNSX zone with the new server information.
Changing a DNSX authoritative server for a zone will cause the BIG-IP to stop serving data from the original server and trigger a transfer request to the new server to obtain new data.
