4.0 to 4.1 - Spree — ContextQMD

<Note> If you're on an older version than 4.0 please follow previous upgrade guides and perform those upgrades incrementally**, eg.

Update gems

Run the following command to update your gems to 4.1:

bash

bundle update

bash

rake railties:install:migrations

bash

rails db:migrate

You have two options:

Spree 4.1 comes with a completely new mobile-first ultra-fast Storefront powered by Turbolinks.

To replace your current frontend with the new Spree UI follow these steps:

In your project root directory run:
bash
```
 rails g spree:frontend:copy_storefront
```
WARNING this will overwrite your current project templates, it's required for the new UI, so if you'll be asked by the generator what to do please choose A to proceed
Next, you will need to copy over two files:
- spree_storefront.rb to config/initializers/spree_storefront.rb
- spree_storefront.yml to config/spree_storefront.yml
If you overwrote any spree_frontend controllers you will need to either remove your local copies or move your custom logic to decorators
The same goes for helpers
You will also need to remove this line:
javascript
```
 //= require spree/frontend/spree_auth
```
from vendor/assets/javascripts/spree/frontend.all.js file

If you wish to not move to the new Storefront UI it's still an option. Just proceed with the steps described below.
