Ok I have been putting this off for awhile but decided to finally do it. I want to make sure this goes smoothly, optimally no downtime of the site no downtime of my email.
I am transferring the domain from 1and1 to namecheap. At the same time I am going to change the host from x10 to hostgator. I have initiated the transfer which will complete in 5 days. In hostgator (the new host) I created an addon domain and will ftp the files over. For the website I believe I just need to tell namecheap to use a different dns than the one I am currently using with 1and1.
For email I use a separate host. Currently my email domain is verified by a cname record and I have an mx record to direct to my email host. What I am unsure of is whether I can copy this verification record right over to the new host, I don't see why not. Specificaclly I have a cname record "randomstring123.mysite.com" and the random string is the verification. This cname verification must be standard, but I really want to be sure I don't need to regenerate this record for my new host (I currently would have to decouple from the domain and then recouple with it to do that - which leads me to think it is unnecessary).
So I have recreated the cname and mx records and will ask namecheap to go to the new dns. Am I missing anything? With this be seamless?
