- [ ] Have rollback plan ready

### Post-Migration

- [ ] Monitor search quality and relevance
- [ ] Tune ranking and boosting settings
- [ ] Set up regular crawl schedules
- [ ] Configure backup and disaster recovery
- [ ] Document new search architecture
- [ ] Train users on new admin interface
- [ ] Decommission old search system (after validation period)
