Greets All !
So I have a 2-node RAC cluster running 11.2.0.3. The veep has issued a directive to change the 'domain name' of the network domain, to reflect the new company branding.
I understand the typical procedure is to remove node 2, deconfigure node 1. Update system(s) with new domain name, reconfigure node 1, then re-add node 2.
Just wondering if there is a way to do this with less impact, a silver bullet as it were.

I am preferring something with a cleaner rollback in case of issues, as I must implement it in production and there are no non-production environments available to test.
I'm also wondering if it's even necessary. Couldn't my team just add an alias for the new domain name (ie stand up a new dns server with the same ip's ?)
I look forward to hearing thoughtful feedback.
TIA
