31 days of Drupal migrations

For the month of August, 2019, we published a series of blog posts to cover Drupal migrations. It covered basic concepts and different use cases. The posts are available English. We are currently working on translating them to Spanish and French. Many thanks to Agaric.coop, Drupalize.Me, and Centarro.io for their sponsorship of this series.
