Hi

I was wondering how hard it is to move all websites on one cpanel server to another server that has cpanel?

What if I have resellers who have their own nameservers on my server?

I have resellers which have their own nameservers and then I have regular hosting accounts which have my own nameservers

Any help would be appreciated. Also any info on downtime from moving servers or any suggestions.

If you keep both boxes up then there would be practically no downtime. Just mirror the entire thing over then once its good to go change the A records for the domains to point to the IP of the new box. Once all domains are pointing to the new IP(s) its all fine and dandy and nobody will even notice. I've never used CPanel so I'm not sure how to go about it through that but its quite easy to do manually via the command line. I've done 2 or 3 transfers like this. Only had 10 minutes of downtime the first time because a few permissions weren't retained. If the new box is going to be the nameserver as well as webserver you may have some downtime when transferring the records...

Using move function in CPanel it's pretty easy to move from A to B server. If you have a large amount of sites on them, you're bound to run into time constraints. Even if both server are running 10m/s, it will take (average) 3-5 hours to move 2-300 accounts. Of coursel, that's assuming you've got a LOT of accounts on this server as well.

DNS wise, as was said, you can simply change the records, or change the ip address manually for each site in DNS settings (which could get to be a pain). The downtime there should be extremely minimal if you do both.

so if I change the ip for ns.mydomain.com and ns2.mydomain.com will all sites on those nameservers be changed as well?

Ya, if you update your ip's at glue as well.

what is glue?
