I had first attempted a migration of my site back when Drupal 8.0 was released but had a few issues. With Drupal 8.3 it was nearly flawless (maybe even 8.2, but I had put the idea back burner.) I did have some interesting issues to workaround ## Missing filter plugins My migration process was halted and littered with errors due to missing plugins, specifically around my text formats. The culprits were: - Media 2.x and media filter - GitHub Gist filter - OEmbed filter - Twitter links and usernames These plugins were missing from my code base so I had to replicate them. The Twitter module has been ported, but I didn't have a need for it anymore, so I wrote skeleton Filter plugins that had no functionality. However, I relied heavily on the others. For the Media filter, I had tried to follow the solutions in [Kalamuna's blog post](https://blog.kalamuna.com/news/converting-drupal-7-media-tags-during-a-drupal-8-migration). However, it did not quite work (not a custom migration.) So I opted for a custom Filter plugin which provides the same functionality as the Drupal 7 filter: convert a shortcode to an image embed. The [Gist Filter module](https://www.drupal.org/project/gist_filter) has yet to be ported, so I quickly wrote my own version. The same was true for the OEmbed module. It has a port to Drupal 8 started but was not stable. Luckily I was able to use the *alb/oembed* library and the OEmbed module's Filter plugin. All I needed to do was change library references. I made sure to document this . A full example of my workarounds can be found in  ## Executing the migration Other than that, it was as simple as running the following command provided by Migrate Tools: ```bash drush migrate-upgrade \ --legacy-db-url=mysql://root:root,@mysql.dev/glamanate_d7 \  --legacy-root=http://glamanate.com ``` I also found it useful to provide a custom installation profile during the trial and error process. I patched Drupal 8 to [allow a profile to be installed from existing config](https://www.drupal.org/node/2788777). When you run a migration all configuration will be migrated. This allowed me to run my migrations, tweak config, export, and then re-import when the process was done. ## Summary and what is next Overall it was fairly smooth. I spent more time porting over the Media embed filter. I didn't bother to fix the actual post content but port the functionality verbatim. I'd say I spent roughly a day overall on this migration. More time was spent rewiring a new theme, which is not finished. My main motivation was to have an improved authoring experience, thanks to Drupal 8 and CKEditor. I'd like to expand my publishing efforts to provide more tutorials and deep dives into topics. ![](/themes/custom/mglaman/images/headshot.webp)Thanks for reading I write about Drupal, PHP, and the quiet infrastructure behind large sites — caching, config, and testing.
