I just ordered the server and discovering how the things are working.... Sorry, if my questions sometimes will be foolish - but I didn't find the answers on the forum.

I have domains that are on another host. My steps to transfer them in full to the EV1 servers:

[list=1]
[*]Change both nameservers to ns_.ev1servers.net [DONE]
[*]Add domains in the Plesk control panel [DONE]
[*]Wait for the dns propogation [WAITING]
[/list=1]

If I'm correct?

But what is the "DNS Configuration" while I'm logging into EV1 Servers Members Area? There I can add the domain(s) to DNS of RackShack and/or EV1 Servers.

Is the equal to the Plesk DNS or not?
If I NEED to add ALL domains manually in this Members Area?
Or just main one?
Or needn't at all?

Please, someone explain me this! Thanks.

yes, you need add all the domains which are in your plsk panel in to this dns configuration.

after you add them all, you can list them with status under the same dns configuration link. And be patient to wait for some period up to 5 hrs, your domain will be resolved to your server' ip

yes, use the EV1 dns.

It'll take up to 72 hours for it to work.

IF I understood you correctly I need to log-in to RS Members Area and add domains there, right?

I needn't to use Plesk DNS management, right?
