 * I used this plugin to move a site from an old domain to another. I thought that
   it would update the old url to the new url. However, if I look at the _posts 
   table. However, the guid table did not get replaced. I can do that via a sql 
   query but I just wanted to make sure is this expected and what other potential
   issues I could have.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmigration-issues-questions%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@dexdeadly](https://wordpress.org/support/users/dexdeadly/),
 * Thanks for your feedback.
 * There is a statement of GUID in WordPress.org document ([https://wordpress.org/support/article/changing-the-site-url/](https://wordpress.org/support/article/changing-the-site-url/)):
 * The term “GUID” stands for “Globally Unique Identifier”. It is a field that is
   intended to hold an identifier for the post which a) is unique across the whole
   of space and time and b) never, ever changes. The GUID field is primarily used
   to create the WordPress feeds.
 * The second part of that is that the GUID must never change. Even if you shift
   domains around, the post is still the same post, even in a new location. Feed
   readers being shifted to your new feeds when you change URLs should still know
   that they’ve read some of your posts before, and thus the GUID must remain unchanged.
 * **Never, ever, change the contents of the GUID column, under any circumstances.**
 * So, our plugin keeps GUID unchanged in migration process.
 * Regards.
