After migrating to analytics.js, you can take advantage of advanced tracking features like cross-domain tracking, enhanced ecommerce tracking, and user ID tracking.
Remember to always keep a backup of your previous ga.js tracking code and consult Google Analytics documentation for any specific requirements or additional steps during the migration process.
