hi, i've had the same issue come up a couple of times recently and i'm looking for a bit of advice before i go any further. i'm doing web development on a couple of websites where the companies want to preserve the mail exchange set up with their existing hosts, but wish to move their website to a different hosting platform. i have just set up a VPS which i want to host the websites on, however, i am unsure if i can simply request that the existing providers change the www record to point to my VPS IP address. is this sufficient or do i have to ask the hosts for a nameservers change?
