WordPress migrating to another server and/or setting up test environment

In most projects, it is wise to work from the OTAP method (Development, Test, Acceptance and Production). How to quickly put a copy on another server (and domain) from the development environment. There are, of course, several methods for migrating. Here below we describe 1 .

WordPress rapid migration :

• 1. Download all files (that are e.g. in public_html or private_html) with an ftp program. You can use the free ftp program filezilla for this purpose : https://filezilla-project.org/
• 2. Back up the database. This can be done through phpmyadmin. Only if you have a large database then it is recommended to use another program for this purpose (There are numerous programs available. E.g. Navicat for mysql, MySQL Workbench etc.. or the free script BigDump)
• 3. Upload the files to your new server (and domain) using the ftp program. In most cases this is the same folder (e.g. public_html or private_html)
• 4. Import the database on your new server
• 5. In the wp-config.php file, modify the database information

   
  /** The name of the database for WordPress */
  define('DB_NAME', 'NIEUWEDATABASENAAM');
  /** MySQL database username */
  define('DB_USER', 'NIEUWEGEBRUIKERSNAAM');
  /** MySQL database password */
  define('DB_PASSWORD', 'NIEUWWACHTWOORD');
  /** MySQL hostname */
  define('DB_HOST', 'localhost');
  

• 6. In the database in table wp_options, adjust the value of siteurl with the new domain. (https://www.oudedomein2016.nl to e.g. new https://www.nieuwedomein2017.nl)
• 7. You can now log in to the backend of your website
• 8. In some cases, certain reference to the old domain in the content and/or media files should be replaced with the new domain. You can use this plugin for this purpose : https://nl.wordpress.org/plugins/search-and-replace/
• 9. Should some plugins use a root reference, you should adjust this in many cases you can deactivate this plugin and reactivate it again. This will usually automatically update the new root reference.
• 10. Other obstacles may be certain directory permissions (cache/upload) that you may still need to adjust when they are uploaded on your new server.
