Migrate to Elastic Beanstalk v3

v3 is FAR better than v2

You installed v2 by adding some directory to your PATH, remove that and run sudo pip install awsebcli

Blow away your .elasticbeanstalk/ folder and run eb init new-name to start from scratch.

init sets up a new key pair and you can run eb ssh to get to your EC2 instance(s)

You can configure your app through the UI or by running eb config new-name to edit the yaml configuration file, this will apply the changes when you save and quit.

The UI and yaml file are kept in sync :)

You can clone environments with eb clone new-name this lets you set a "CNAME" (readable URLs!) for the new environment.

You can switch the old environment URL to use the new environment with eb swap old-name which may take a few minutes.

use eb -h for docs.
