Tracking changes in Migrate with dynamic row hashes Thursday 27, September 2018 mglaman

When it comes to Drupal and external data, I use Migrate. A lot. Like a lot, lot, lot. Many times this data is being imported over CSV files that are pushed to a server at some defined interval. Usually, the data can be derived directly from the CSV file itself, other times a custom process plugin derives data from other information. Drupal's Migrate system has two steps to check if new data should be imported or skipped. First, you can tell the migration source to track changes for each row. Then, if you are tracking changes, it hashes each row of data to see if it has been changed.

MigrationWTF: Specified key was too long; max key length is 3072 bytes

I recently hit a curveball with a custom migration to import location data into Drupal. I am helping a family friend merge their bespoke application into Drupal.

Missing filter plugins

My migration process was halted and littered with errors due to missing plugins, specifically around my text formats. The culprits were:

Drupal Commerce and Migrate status

First Steps

Plans were made back in December 2015 to put effort into the ability to support Migrate with Drupal Commerce to speed up adoption of Drupal Commerce 2.0. Commerce Migrate for Drupal 8 will provide migrations from Drupal Commerce 1.x, Ubercart for D6, and Ubercart for D7. Ideally, this module will also support other vendors, such as Magento and WooCommerce.

Migrating WordPress to Drupal

Right now two of the most popular open source content management systems are WordPress and Drupal. WordPress is very simplistic and easy to roll out, which is why there is nearly 80,000,000 websites using WordPress. Then you have Drupal which is a more robust content management system that needs a little bit more love to get things moving.
