DNS Changes and Multiple Domains
Good afternoon everyone, I'm hoping to get some great feedback on how to handle an upcoming server change. (It's tomorrow)
What we're doing is moving a major web site to a new server, changing NameServers, and we have three domains that point to the information. Here are my questions.
What is the best way to avoid downtime of the site? Should we have our old DNS point to the new server IP and make the Name Server changes at the same time? Should we stutter step all of the changes?
Second, we eventually want to weed out all two of the three domains, mainly to improve our actual IBL count and to avoid duplicate content issues of course. What is the best way to slowly get out from under those domains?
Right now each actually have IBL's to our site, and not a small amount, so we need to slowly work to clean that up.
Is the best thing to do, point all three domains at the same content, then do a mod-rewrite or 301 redirect of the two domains we don't want to the one we do?
I want this to go smoothly so any help would be greatly appreciated.
