The Drupal 8 EOL date is November 2nd 2021. This is because Drupal 8 has a dependency on Symfony 3 which has an end-of-life in November. That means there will be no further security fixes implemented, so to keep your project safe and secure against potential threats, it is strongly advised to upgrade to the latest version of Drupal. Works like a charm. I migrated two drupal installations from sqlite to mysql and I noticed a performance improvement. Just a couple of notes (if they might be of help), take the site offline before doing the migration and in my case at least, I had to disable secure pages, Locale and uninstall the Spanish language pack, then reinstalled them back again.

- Install the plugin in the Admin => Plugins menu => Add New => Upload => Select the zip file => Install Now
- Activate the plugin in the Admin => Plugins menu
- Run the importer in Tools > Import > Drupal
- Configure the plugin settings. You can find the Drupal database parameters in the Drupal file sites/default/settings.php
I get the message: “[fg-drupal-to-wp] Couldn’t connect to the Drupal database. Please check your parameters. And be sure the WordPress server can access the Drupal database. SQLSTATE  Access denied for user ‘xxx’@’localhost’ (using password: YES)”
- First verify your login and password to the Drupal database.
If Drupal and WordPress are not installed on the same host:
- If you use CPanel on the Drupal server, a solution is to allow a remote MySQL connection.
- go into the Cpanel of the Drupal server
- go down to Database section and click “Remote MySQL”
- There you can add an access host (WordPress host). Enter the access host as the SOME-WEBSITE-DOMAIN-OR-IP-ADDRESS and click add host.
- Another solution is to copy the Drupal database on the WordPress database:
- export the Drupal database to a SQL file (with phpMyAdmin for example)
- import this SQL file on the same database as WordPress
- run the migration by using WordPress database credentials (host, user, password, database) instead of the Drupal ones in the plugin settings.
I get this error when testing the connection: “SQLSTATE[HY000]  Connection refused” or “SQLSTATE[HY000]  No such file or directory”
Drupal Sqlite Database
- This error happens when the host is set like localhost:/tmp/mysql5d.sock
Instead, you must set the host to be localhost;unix_socket=/tmp/mysql5d.sock
The migration stops and I get the message: “Fatal error: Allowed memory size of XXXXXX bytes exhausted” or I get the message: “Internal server error”
- First, deactivate all the WordPress plugins except the ones used for the migration
- You can run the migration again. It will continue where it stopped.
- You can add:
define('WP_MEMORY_LIMIT', '512M');in your wp-config.php file to increase the memory allowed by WordPress
- You can also increase the memory limit in php.ini if you have write access to this file (ie: memory_limit = 1G). See the increase memory limit procedure.
The media are not imported
- Check the URL field that you filled in the plugin settings. It must be your Drupal home page URL and must start with http:// or https://
The media are not imported and I get the error message: “Warning: copy() [function.copy]: URL file-access is disabled in the server configuration”
- The PHP directive “Allow URL fopen” must be turned on in php.ini to copy the medias. If your remote host doesn’t allow this directive, you will have to do the migration on localhost.
I get the message: “Fatal error: Class ‘PDO’ not found”
- PDO and PDO_MySQL libraries are needed. You must enable them in php.ini on the WordPress host.
Or on Ubuntu:
sudo php5enmod pdo
sudo service apache2 reload
I get this error: PHP Fatal error: Undefined class constant ‘MYSQL_ATTR_INIT_COMMAND’
- You have to enable PDO_MySQL in php.ini on the WordPress host. That means uncomment the line extension=pdo_mysql.so in php.ini
Does the migration process modify the Drupal site it migrates from?
- No, it only reads the Drupal database.
I get this error: Erreur !: SQLSTATE[HY000]  Unknown system variable ‘NAMES’
- It comes from MySQL 4.0. It will work if you move your database to MySQL 5.0 before running the migration.
I get this error “Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM”
- You must use at least PHP 5.3 on your WordPress site.
I get this error: SQLSTATE[HY000]  The server requested authentication method unknown to the client
- It is a compatibility issue with your version of MySQL.
You can read this post to fix it: http://forumsarchive.laravel.io/viewtopic.php?id=8667
None image get transferred into the WordPress uploads folder. I’m using Xampp on Windows.
- Xampp puts the htdocs in the applications folder which is write protected. You need to move the htdocs to a writeable folder.
Do I need to keep the plugin activated after the migration?
- No, you can deactivate or even uninstall the plugin after the migration (for the free version only).
