This guide has been written from the perspective of a blank Spree 2.0 store with no extensions.

If you have extensions that your store depends on, you will need to manually verify that each of those extensions works within your 2.1 store once this upgrade is complete. Typically, extensions that are compatible with this version of Spree will have a 2-1-stable branch.

This is the first Spree release that supports Rails 4 exclusively. Spree releases after this point will continue to support Rails 4 only.

Upgrade Rails

For this Spree release, you will need to upgrade your Rails version to at least 4.0.0.

It is recommended to read through the Upgrading Ruby on Rails guide to learn what needs to be done for your application to migrate to Rails 4.

gem 'rails', '~> 4.0'

Upgrade Spree

For best results, use the 2-1-stable branch from GitHub:

gem 'spree', '~> 2.1'

Run bundle update spree.

Copy and run migrations

Copy over the migrations from Spree (and any other engine) and run them using these commands:

    rake railties:install:migrations
    rake db:migrate
