Should I delete old DNS records

#1

My client just switched hosts and now we have only the A record and CNAME www pointing to the new host. We no longer need all the other A records that are still pointing to the old host (ftp, mail, webdisk, whm, etc.) - can I safely delete them?

Hi @dac,

If services are not in use, deleting their DNS records should not cause problems.

However it is critical to make a full backup of the zone in case you need to restore the deleted records.
