It used to be that you had to upgrade in multiple steps, but not anymore. You can upgrade directly from 1.12.0 to 1.13.2
Make sure you backup your database
Upgrading is not possible from general upgrade doc for who are hosted in heroku.
can anyone guide ???
@Varun-Ganesh-D what issue are you running into? What deployment process did you follow?
