We currently have a number of clients that are pointing their domains at our old nameservers, for this example they are:
We have moved the server to a new provider (the old server is still running) and the new provider have their own nameservers and I no longer require "whitelabel" nameservers.
The majority of domains that point to our servers are in our control, so I can simply point those to the new nameservers. However, there is a small number of domain names that we don't control that will need updating. Some clients are notoriously slow at making these changes, or they simply don't know how to do it.
What I am intending on doing is basically pointing the original nameservers at the new providers nameserver IP addresses. For example, if the new providers nameservers are as follows:
NS1.NEWSERVER.COM > 18.104.22.168 NS2.NEWSERVER.COM > 22.214.171.124
can I simply point the old nameservers at the above IP addresses and it will work the same way as re-pointing the domains at the new nameserver?
NS1.OLDDOMAIN.COM > 126.96.36.199 NS2.OLDDOMAIN.COM > 188.8.131.52
Any help or advice is greatly appreciated!
