When Your Domain Name or URLs Change
When your domain name or URLs change - i.e. from http://example.com/blog
, or http://example.com
- there are additional concerns. The files and database can be moved, however references to the old domain name or location will remain in the database, and that can cause issues with links or theme display.
If you do a search and replace on your entire database to change the URLs, you can cause issues with data serialization, due to the fact that some themes and widgets store values with the length of your URL marked. When this changes, things break.
