- install/migrating: convert to a hub page with three clear paths (CardGroup for cross-system imports linking Claude+Hermes, machine-to-machine move with Steps and AccordionGroup, plugin upgrade Card linking Matrix)
- install/migrating-claude: align with Hermes page structure (add Restart-and-verify Step, JSON output for automation, Troubleshooting AccordionGroup with 4 entries, cross-link to Hermes guide)
- cli/migrate: tighten intro to mention both bundled providers and link the migration hub
- docs.json: move Maintenance group to immediately after Install overview, nest the four migrating pages (migrating, migrating-claude, migrating-hermes, migrating-matrix) under a 'Migrating' subgroup so they collapse into a dropdown
