Update 2010: How to Move WordPress to a Different Server and Web Address
The following video demonstrates how to move your WordPress blog from one server to another and change the web address. This is an updated video from one I did a few years ago here. This video addresses the issue of changing the web address in the database where that information is entered as serialized data. To learn more about serialized data in WordPress, just use Google, but in short, if you use a text editor to do a search & replace of the url in the database dump–like I demo in the old video–then you will have problems with text widgets not coming over and you may have problems with values in some of your plugins. Using the procedure demonstrated in this new video should solve those problems, thanks in large part to the script provided at Spectacu.la. Download that script here for use as demonstrated in the video below.
