How to copy an existing wordpress to a new domain name

If you need to copy a wordpress site to a new domain,  you can do so with the following steps.

1. Download a copy of their document root from the source folder
2. If they have a website on the destination folder already, create a backup of it. Either rename the folder to foldername.out and make a new foldername, or make a tarball of the folder (tar cfz foldername.tar.gz foldername)
3. Upload the files you downloaded in step one to the new document root
4. Look in the wp-config.php file for the old database name, database username, and database password
5. Create a new database in the new cpanel account. Create a new username and password as well. Typically, I just create them with the same database name, username and password so that I only have to change the part before the _ in the username and database name
6. Assign the new username to the new database name
7. Export the database from the old site
8. Open the .sql file in wordpad and do a search and replace
   1. Search for /home/UserName/public_html/ (or whatever the path is to their old document root)
   2. Replace with /home/NewUserName/public_html (or whatever the new path is to their document root)
   3. Search for domain.com
   4. Replace with newdomain.com
9. Now, import the .sql file into the new database you created in step 5.
10. Update the wp-config.php in the new document root to use the new database name, username, and password
11. Chown the files in the new document root to the new username
12. Test the site to make sure it works
