Migrate from Heroku to Voroa
What moving an app off Heroku actually involves: your buildpack, config vars, add-on database and custom domains, and how each of those maps onto Voroa.
What this covers
Moving an application off Heroku is four separate jobs, not one. Your buildpack has to be replaced by whatever the new platform uses to detect and build your language. Your config vars have to be recreated as environment variables. Any add-on database has to be dumped and restored somewhere else, with a short window where writes must stop. Finally your custom domain has to point at the new service, and a new certificate has to be issued before you switch DNS over.
A step-by-step Heroku migration guide, and any tool that reads your config vars or add-ons for you, is not available on Voroa today. Each of the four jobs above can be done by hand using the guides below.
