Moving a wordpress.org website to another domain name?

Here is my solution.

First download this file.

Then follow these steps.

In shortly

1. Backup/download your database.
2. Upload it to your new site.
3. Copy all wordpress folder including wp-admin,wp-content etc from
   your old site to new one.
4. Edit the downloaded php file, change the password. you need to
   change the password in this line. define(‘DDWPDC_PASSWORD’,
   ‘Replace-This-Password’);
5. Now place the downloaded php file in the root directory of your NEW
   site.
6. http://www.yourNewDomain.com/wp-change-domain.php
7. Enter the password you entered in step 4.
8. Now you can see a form filled with your old db values. Just change
   the details. Thats it. You are done.
