I am trying to migrate my nameservers from GoDaddy to Amazon Route 53. I would like to edit my DNS record to first add the Amazon Route 53 servers, let that propagate, then remove the GoDaddy servers.
Is it acceptable for my DNS record to have multiple nameservers on different hosts with different top-level domains, provided they all return identical Zone files (ie they all return the same A, CNAME and MX records)? GoDaddy said it could break things, but couldn't explain how.
Thanks,
-Eric
