I'm switching from 1and1 to Dreamhost and I am looking for the best way to change over DNS with minimal or no interruption of services. What are the appropriate steps?
So far I haven't changed 'transferred' the domain. I have the domain loaded on Dreamhost, configured all the settings, then went to 1and1 and changed the name servers to Dreamhost, but none of the records would resolved after 6 hours, so for now I changed everything back.
I remember when I switched to 1and1 last year, I wasnt able to add the domain to 1and1 until after it completed the transfer which happens randomly it seems (5-7 business days), and when it finally transferred, it happened to do it during the middle of the business day, and killed our email and website for ~3hrs.
Is there a way I can move DNS with no noticeable impact to users?
