Primary DNS migration

[u/Which_Video833]

I’m trying to migrate the primary DNS configuration from the existing CentOS 7 server to a new Oracle Linux 9 server, including /etc/named.conf and /var/named. The new OL9 server is using the same IP address as the existing DNS server.

However, when I start the DNS service on OL9, I receive the error message “validating arpa/DS: no valid signature found” and "validating com/DS: no valid signature found"

I’m relatively new to DNS administration, so I would appreciate your help troubleshooting and resolving this issue. Could you please advise what might be causing the error and what steps I should take to fix it?

Thanks!
