    I want to move a single account from one server to another. I read in other topics that when I change the nameservers with my domain registrar it is advised to edit the dns zone for this domain in WHM, so that the domain will point to the new server without delay.

    Since I'm new to this, I'm not sure what to do here.
    I find the lines below when clicking the option 'edit a dns zone':

    domainname.com 14400 IN NS me.server400.net
    domainname.com 14400 IN NS metoo.server400.net
    domainname.com 14400 IN A 123.123.123.123
    localhost.domainname.com 14400 IN A 127.0.0.1
    domainname.com 14400 IN MX 0 domainname.com
    mail 14400 IN CNAME domainname.com
    www 14400 IN CNAME domainname.com
    ftp 14400 IN A 123.123.123.123

    Can someone explain to me which fields to edit, and what to fill out there?
    Also I curious about what the meaning of the following is: NS, A, MX, CNAME?

    thanks in advance!

    Above and to right of that info in the zone file you will see something like this:

    @ IN SOA %nameserver%. %rpemail%. (
    %serial% ; serial, todays date+todays
    14400 ; refresh, seconds
    7200 ; retry, seconds
    3600000 ; expire, seconds
    86400 ) ; minimum, seconds


    Generally what is being discussed is to lower the "TTL" setting (minimum. seconds) to something like 300 (seconds) so that when you move the domain the dns propagation will happen quickly. Once you have lowered that value for 24-48 hours you can then point the domain "A" record to the new IP address. Depending on whether you have dynamic content (mysql databases) to move then the process is fairly straight forward.

    Here is a link to another forum where this has been discussed.
