How to install/use

Commerce Backoffice Product replaces the product view, while Commerce Backoffice Order replaces the order view.
If you've made manual changes to the existing views, then they won't be replaced, and you will need to disable them manually (in the views listing) in order to get the new views to show up.

Can you explain, which EXACTLY views I must disable, and when - just before installing Commerce Backoffice, or it is possible disable they after install? I have few of 'product' views - one for main page, admin 'product' view and VBO product view. Same situation for the Orders view.

If you install Commerce VBO then you need to uninstall it first and disable all of the view that Commerce VBO generated, (admin/commerce/*...) But not disable the commerce backoffice view

here it's a Commerce Backoffice tutorial that should provides all the explanations needed.

This link should be on project page : https://drupal.org/project/commerce_backoffice .

Thanks vasike,

But that video doesn't go over any information related to the OP issue, very informative though on the changes. I too just enabled the module and haven't seen any changes. But once I disabled the original Orders view, and cleared cache, it worked.
