Change the area of ​​the hero after creating

Question

Thought it might work, but it’s not:

heroku appname --region=eu 

This works, but I already have an existing application, so it makes no sense to me:

 heroku create --region eu 

Or for the addon:

 heroku addons:list --region=eu 

Answer 1

You can do this by opening the application. Take a look at the Heroku documentation here: https://devcenter.heroku.com/articles/app-migration

Answer 2

There is no own ability to simply switch, but there is still a way to do this.

Create an application branch in the region you need.
For example, you have an application in the US region and you want to transfer it to the EU:

• Run this command to create a new application that will be a copy of the existing one:

 heroku fork --from sourceapp --to targetapp --region eu 

• After checking the performance, check (and if necessary copy and paste) the settings, permissions, additions, etc. They can also be copied, but it is better to check.
• Rename sourceapp to something like sourceapp_old .
• Rename targetapp to sourceapp .

NOTE. But this method has several disadvantages:

• it does not migrate the database (but there is a method how to handle this )
• there may be problems with DNS and SSL
• if the web server is working - you need to use the service mode

In any case, I would recommend reading the official Heroku documentation before committing risky actions like this.
