Dear Chirs and anyone who has ideas,

My app was developed a long time ago, in version 3.4.0 through the Heroku-18 stack. But I just found the stack was ended in Heroku. Is there an easy way to upgrade my app or adjust my settings? 

Thanks in advance for your help!

Best,
Jin

Hi, 

I think you must just go to "Settings" in Heroku and update the stack there. I think there should be an option for it. Otherwise, perhaps consider creating a new app?

Best,
