Custom Drupal data migration: a Georgia GovHub story
summary
Drupal 7 multisite content from 85+ sites moves into a Drupal 8 multisite in phased batches of about six sites over two-week cycles, preserving node IDs and migrating unpublished content so links don’t break. Work uses core migrate plus a ga_migrate suite, Lando, Tugboat previews, CircleCI/Quay, and custom tools migration planner and SQueaLer. Complex solutions include a ga_migrate_site override module for site-specific hooks, a GA microcontent to text process plugin that renders nested paragraphs to entity-embed markup, and pseudo-field stubs to resolve circular dependencies.
