Of all the APIs available in Drupal, the Migrate API may be one of the most hidden from the average Drupal user. It is even possible that, while reading this post, you discover for the first time that there is a whole set of Drupal modules, both core and contributed, fully dedicated to designing and running migration processes inside Drupal. You can move data from an old Drupal site to the most recent version, but also from other databases, files, systems, frameworks, CMSs, DXPs… and all of these options come together around the Drupal Migrate API. It is a set of resources that demands …

Drupal Migrations (V): Debugging Migrations-II

Mon, 27 Jul 2020 00:00:00 +0000

Following the previous post, in this article I wanted to share again some guidelines for debugging Drupal Migrations. While in the last article I wrote down some questions about modules, plugins and configuration object management, in this case I felt like stopping at something more “code-oriented”, more specific. I have chosen for this article some guidelines to configure Xdebug in an IDE (in this case I have used PhpStorm) for migrations running in a locally deployed Drupal using DDEV. With the aim of debugging a Migration process -although actually the process is similar for any …

Drupal Migrations (IV): Debugging Migrations-I

Mon, 29 Jun 2020 00:00:00 +0000

The Drupal migrations, despite their linearity in terms of definitions, contain a lot of inherited complexity. The reason is very intuitive: although the Migrate API is a supersystem that offers a very simple “interface” of interactions for the user-developer who wants to build migration processes, in reality several subsystems work by interacting with each other throughout a migration process: Entities, Database, Plugins…There are a lot of classes involved in even the simplest migration process. If we add the irrefutable fact that a migration will tend to generate errors in …

Drupal Migrations (III): Migrating from Google Spreadsheet

Wed, 27 May 2020 00:00:00 +0000

The systems and subsystems related to Drupal’s migration API are certainly exciting. In the previous articles in this series, I wanted to draw as complete a map as possible (part one) of the vast amount of resources, possibilities and referenced experts. In the second part I wanted to expose some basic mechanics of the migration processes in Drupal and knowing that this opens the door to thousands of options, possibilities and techniques….I didn’t want to let a third article go by without sharing some experiences migrating data from a common format as a Google Spreadsheet, …

Drupal Migrations (II): Examples

Tue, 17 Mar 2020 00:00:00 +0000

As I said in the previous post, during these months I will be playing with migrations and preparing a few cases for a future book, I hope. During these days of confinement, I want to keep publishing small articles here to share migration-related experiences.

In the previous post, I wrote about Drupal migrations from a toolbox point of view: a set of basic resources to help frame a migration.

There is a lot of information to process, and of course there are more concepts, techniques, and tactics involved in solving a migration. So this month I want to write something that lets me play with …

Drupal Migrations (I): Basic Resources

Tue, 25 Feb 2020 00:00:00 +0000

I am working on notes for a draft that should become a book about migration processes built with Drupal and its Migrate API. It is expected to be released in June 2020, and collecting, testing, and shaping the content has become quite a large piece of work.

There are still a few months left before launch, so, to preserve a little mental health and give these tasks some partial meaning, I thought I could publish a few small posts here, based on those working notes.

That way I can share something useful alongside the complementary notes and, if COVID-19 gets me before the book comes out, at …
