We just finished a D7 → D10 migration for a federal agency: 40k nodes, 120k files, 14 languages. What I'd do differently:
- Migrate files first, separately, with
--continue-on-failure - Write process plugins, not hook_migrate_prepare_row spaghetti
- Run migrations nightly against prod data from week one
- Build a content diff report early, so editors can sign off section by section
drush migrate:import --group=agency_content --update --feedback=500
Happy to answer questions.
