Copy/ Move the files to the new domain. Open your wp-config.php file. On your new server, create a database with the same details — or create a database with different details, then update your wp-config.php file.

Once you are finished with that

• Backup your database and save the copy off-site.
• Login to phpMyAdmin.
• Click the link to your Databases.

UPDATE wp_options
SET option_value = REPLACE (
option_value,
'<old_domain>',
'<new_domain>')
WHERE option_value LIKE '<old_domain>'
