I have 5 cPanel servers
1x main web,mail,sql,etc...
4x dnsonly for nameservers
my main webserver is in a dns cluster setup with BIND and write-only role.
DNS Path Diagram:
cpanel-main.exampledomain.com
-> ns1.exampledomain.com
-> ns2.exampledomain.com
-> ns3.exampledomain.com
-> ns4.exampledomain.com
....... so to be clear... my main is only writing to ns1 .... and then the ns1 will sync to ns2,ns3,ns4
I'm getting ready to migrate all accounts to a new CP server/new public ip network.... although it will be on the same hardware(hyper-v host, with dual NIC, dual WAN, dual vm's).
The old server is behind a very slow vdsl connection and it is behind NAT.
the new is not behind NAT.
I have manually configured the new cPanel server with cloudlinux8, and I think its ready... and i'm really excited to begin the migration process ;-)
so.... my main concerns are my nameservers and the DNS cluster setup.
I want to keep using my nameservers/dns-cluster on my new webserver, because I have soooo many records.
I will not be migrating ALL accounts at once.... just few accounts every day to be safe.
so how should I go about this,,, so that my new cPanel will be on the same dns cluster without overwriting the old dns records except the ones I migrate day-to-day ?
can I just connect my new server as write-only to the same dns-cluster with same settings as my old-main ? and that would automate the migration process of relative dns records and leave others alone ? that would be awesome, but i'm unsure.
or will it clear my dns-cluster of all records ;-) which would be terrible...
thanks
