Legacy Router End of Life Migration Beginning for Heroku Eco-tier applications
Change effective on 06 February 2025
In November of 2024, our new Common Runtime router became generally available.
Router 2.0 replaces the Common Runtime’s legacy router. We’re deprecating the legacy router and it’ll reach end-of-life in Spring 2025. See the Legacy Router end-of-life FAQ Help article for updates on timelines and information.
At the time of this annoucement, we will begin the first phase of migration of customer applications to the new router. The Heroku platform will begin migrating Eco-tier Common Runtime applications from the legacy router to Router 2.0. There is no action required by customers at this time and another changelog will be posted once all Eco-tier applications have been successfully migrated.
Please note that all customers can migrate their own Common Runtime applications at anytime and ahead of migration timelines by following instructions to enable the new router.
