CauseMaintenance adds MX/A records for the domain
This Hotfix ensures that there are no changes in the MX records. All the entries will remain intact even after the upgrade.
Installation Instructions :
- Copy the file DnsUtility at /root/ location.
- Run command sh DnsUtility -h for viewing the help of the command.
- Run command sh DnsUtility -b before preforming an upgrade operation. This will take backups of all files under /etc/bind/ and /var/named/ locations and store them at /var/lib/dns-backup/ location.
- Run command sh DnsUtility -r after the upgrade operation completes. This will restore the previously backed up zones.
