+## Migration form LinkField v3 to v4
+
+The `Title` DB field has been renamed to `LinkText`
+
+You can manually rename this column in your database with the following:
+
+```php
+// app/_config.php
+
+use SilverStripe\ORM\DB;
+
+// Only run this once
+// This will rename the `Title` field to `LinkText` in all relevant tables
+DB::get_conn()->getSchemaManager()->renameField('LinkField_Link', 'Title', 'LinkText');
+```
