I'm currently fixing a migration issue on Drupal 8 using Drush.
Migration failed with source plugin exception: SQLSTATE[42S02]: Base
table or view not found: 1146 Table
drupaleightbase.migrate_map_upgrade_d7_user doesn't exist:
I have already managed to find a solution and just need to test it. The only thing stopping me is where do I add or place this
mysql configuration code below. I'm still new with migration. I have already placing it on
settings.php. Been reading the migration documentation but I can't seem to find it
$this->source = new MigrateSourceSQL($query, array(), NULL, array('map_joinable' => FALSE));
