I will be moving all my clients from one to another cPanel/WHM servers (different datacenters)

I need to stay with present nameservers so please point me what steps I need to proceed to make this transfer work and not to left my clients in the dark long.

Main thing is to stay with present nameservers as it is simply almost imposible to change so many domain to point to some new nameservers.
If there is any guidance for this procedure , please let me know

Is it possible to move in this simple way:

1. Set news server up with nameservers like old one but with new IPs

2. Transfer all accounts from old server to new one

3. Change nameservers IPs in domain registrar where domain used for nameserver is.
This will turn off old server

4. Delete old server accounts, abandon server

If you do it this way (move everything then change the nameserver IPs), you will face a number of problems. How serious these problems will be depends on the types of site you are hosting.

Here is the method I suggest:

1) Edit your zone records for each domain and set the TTL (time to live) to 60 (1 minute). You can do this from WHM, but a script may be a better idea if you have a lot of accounts.

2) Notify your customers that their sites will be moved to a new server at such-and-such a time. They should avoid making updates to their sites during the transfer window.

2) Wait 48 hours.

3) Move an account to your new server. Ideally this should be done at non-peak times, like 3 AM ET.

4) Edit the zone record (still on your old server) for the account you just moved. Everywhere the IP from the old server appears, change it to the IP for the new server.

5) Repeat steps 3 & 4 for each account.

6) After all the accounts have been moved to the new server, set up your nameservers on the new server and change the nameserver IPs at the registrar.

Thanks a lot

Just one question. Why setup of nameservers on new server is last step. Shouldn't I setup this in the first place . Can you explain why did you put it in last step ?

Yes, you are right. The nameservers should be set up before you begin moving domains, but only change the nameserver IPs after you have moved everything.

You should keep your old server on line for a few days after you change your nameserver IPs to allow time for the change to propagate.

CPanels move script will automatically edit the zone files and put the New IP in place so you do not have to do this.

Cpanel will change DNS records according new IP of the new server, but we are talking about changing DNS zone files on "old" server where IP of new server must be inserted.

I have problems.

In attempt to assign IPs to the nameservers on new server I am getting respons that this nameservers already have assigned IPs and this IPs (from server I want to move from) are displayed.

So it seems that I can not assign new IPs to the same nameservers (but on new server) until I change them in registrar.

Any ideas how to resolve this ?

I learned that IPs for nameservers can be added manually but I don't know how. Please provide me with some steps in that way

Thanks

OK I went to edit /etc/namerserverips and assigned the nameserver IPs.
Then I went to WHM -Edit setup and there I hit Add an A entry for primary and secondary nameservers. This procedure went well but the problem is that no DNS zone for nameservers was created.

What now , do I have to wait sometime or what ?

One more thing. At what point I must start BIND on new server while proceeding this transfer process ?

my time to have the same problem :(

I moved all my accounts from one server to another (different DCs) with no dessynk nor downtime, but they're using the old server DNS to resolve domains to the new server

Now I have just more 48 hours on the old server, because it will be canceled and WHM doesn't let me assign the IPs to the nameservers (they're already assigned to another IP and, although I changed the primary nameserver to point to this new IP, it didn't propagate yet)... since I want to avoid downtime, should I force it?

thanks in advance
