Resource for SharePoint farm upgrade with server name change
Monday, December 16, 2013 at 9:54AM 
This was a question I had someone ask last week regarding how you might handle the situation where you want to change the host name of your SharePoint farm in an upgrade (or just the host name for any web app really) knowing that all embedded links will be broken.
The low hanging fruit is to set a DNS record so that the old and new point to your new server address, but if you want to alter some site names and/or alert users that they have an old, deprecated url instead of just forwarding them on, the solution below might work for you.
The following script is for the node.js platform and, if run on a server with your old host name's resolution, will intercept incoming http requests, map it to your new server, allowing for site renaming and provide the user with a message as well as the new 'best guess' url to what they were trying to reach. It is pretty straightforward and should be relatively easy to modify as needed.
HTTPS (443): This is geared toward standard HTTP traffic, if you need a version to work with HTTPS on port 443, you can find some subtle changes that will be needed in the node.js information here http://nodejs.org/api/https.html.
