Server Migration - DNS

Hi all,

 

I'm migrating to a new server and would like to confirm the below is ok;

 

SERVER_OLD - IP: 1.2.3.4

 - The cPanel account "somehost" manages the domain for my nameservers  ns1.somehost.xyz and ns2.somehost.xyz, these are used by other accounts on the server.

 - cPanel is configured to use

- ns1.somehost.xyz

- ns2.somehost.xyz

 

SERVER_NEW - IP: 6.7.8.9

 - cPanel is configured to use

- ns1.somehost.xyz

- ns2.somehost.xyz

 

DNS Registrar Glue Records (Points to SERVER_OLD)

 - ns1.somehost.xyz -> 1.2.3.4

 - ns2.somehost.xyz -> 1.2.3.4

 

I've transfered all cPanel accounts to SERVER_NEW using the transfer tool, and the DNS records hosted on SERVER_OLD are now pointing to SERVER_NEW, sites are working as expected.

 

I now need to transfer the account for "somehost.xyz" to SERVER_NEW. I'm thinking to transfer the account and NOT use "live transfer", this way the account will be up and running but not actaually live, and DNS would still coming from SERVER_OLD.

 

When I'm ready to switch from SERVER_OLD to SERVER_NEW, I'll update the Glue Records at the Registrar to SERVER_NEW;

 - ns1.somehost.xyz -> 6.7.8.9

 - ns2.somehost.xyz -> 6.7.8.9

 

Then SERVER_OLD can be swicthed off, does this seem acceptable? Have I missed anything?

 

Thank you!

  You are not saying when you change the A Records of ns1.somehost.xyz & ns2.somehost.xyz

  That is more important than the records in the registrar.

  Hi, the A records on SERVER_OLD will always point to 1.2.3.4, whilst the A records on SERVER_NEW will point to 6.7.8.9. I'm thinking that as the Registrar holds the assocation for ns1.somehost.xyz and ns2.somehost.xyz pointing to 1.2.3.4, SERVER_OLD would be used to handle queries, until such a time that the glue record is updated to use SERVER_NEW 6.7.8.9?

  Cheers

  I'd say that you are overthinking this situation.

  Just transfer the somehost.xyz to the new server, make sure that IPs of the ns records in new AND old server point to the new server IP, and change the IPs in registrar.

  After that you should wait at least 48 (or even 72) hours before you close the old server.
  Changes to DNS records will take from 12 to 72 hours to become effective while the new DNS records are propagated worldwide.
