Drupal 7 to 8 custom module conversion
summary
Three months to port a Drupal 7 site (six subsites) to Drupal 8, converting custom blocks/pages/forms/JS and moving from a single DB to multisite databases; custom modules drop from 80→10 modules by replacing field-collection with Paragraph migrations, using YAML routes, plugins/controllers, dependency injection, and libraries for JS/CSS; variables move to config; dozens of extraneous JS files shrink to 20–30 scripts down to ~2–3; page loads fall from 20–30s to 2–2.5s; use drupal console scaffolding and targeted custom migrations.
