Changing DNS after the site is done, will it cause problems?

    Hi

    I have a client who wants the site redesigned (www.client.com). In order to avoid downtime, i thought about creating it using one of my domains i don’t use (www.example.com) and when it’s done, change the DNS details so that they point to the new hosting where i created the site.

    Will this cause problems? Some people told me that the new site will still have the old links of http://www.example.com

    Other people told me that i need to change the database settings.

    What should i do…??

    Thanks

    Yes, you can use the development site to live one.

    Here is the manual, how you may change the site url.

    Another consideration when you change hosting is that the mapping from website names to servers (IP addresses) (the DNS system) is widely cached by the internet infrastructure. You can make for a snappier changeover by reducing this cache retention time as directed at the OLD server well PRIOR to changing the DNS settings at your nameserver host.

    Reduce the TTL (Time To Live) progressively during the day prior to the changeover. Reduce it to 1 hour (3600 seconds), then 12 hours later reduce it to 10 minutes, then 2 hours later reduce it to 1 minute, then 20 minutes later swap over the nameserver settings to the new website host. I suggest that you do it in steps like this because the TTL is only advisory, a server could decide that the requested time is too short and ignore it, and you don’t know what this threshold is.

    There is nothing to do subsequently (except for monitoring how the new site/server perform), except for cancelling the old hosting.

    Hi Ross,

    sorry but i have no idea of what you are talking about 🙂

    I don’t know what the TTL is. Also, i don’t have access to the old hosting server…
