My Heroku app had its shared database upgraded automatically to the dev plan. I then wanted to upgrade the dev plan to the $9/month plan. I did this, and thinking that it would just allow me to have more rows I deleted the old free ‘dev’ addon. Now I think I’ve deleted the database.
I had no backups so I think my only option is to get the data out of the old shared-database. The instructions to upgrade from shared to dev assume you are already on the shared – but I am not. Is there any way to re-upgrade from the shared-database to a dev one?
I ended up contacting support(at)heroku.com.
They fixed it and admitted the upgrade experience is confusing – so watch out when trying to upgrade your plan …
