Is there a way to change DNS records for many domains at once without editing them one by one?
There is an option to switch name servers for multiple domains at once. To do that, please go
Top > Service Director > Domain Manager > Domains, select the domains required, press Change Name Servers and follow the wizard.
NOTE The option works for registered and transferred domains only. For domains registered elsewhere it will result in the message below.
Name Servers cannot be changed for the selected domain(s). Domain(s) are either registered elsewhere or in the 'Unregistered' status.
To make it work for domains registered elsewhere, please upgrade to 4.5.6 and install hotfixes that can be found in the Resolution part of the article After upgrade to 4.5.6 DNS zones are massively removed from OBAS name servers .
