Re: [spree-user] Upgrade process

1. Update gemfile from *gem 'spree', '1.2.4*' to *gem 'spree', :git =>
'git://github.com/spree/spree.git', :branch => '2-0-stable' *
2. Bundle update
3. rake railties:install:migrations
4. rake db:migrate
Then I got the error at homepage:
couldn't find file 'store/spree_core'
(in D:/DevRuby/MyStore/app/assets/stylesheets/store/all.css:7)
Extracted source (around line *#7*):

The content of D:/DevRuby/MyStore/app/assets/stylesheets/store/all.css is
/*
* This is a manifest file that'll automatically include all the
stylesheets available in this directory

this file and they'll appear at

file per style scope.

When I run "git status", the only changes are Gemfile, Gemfile.lock,
db/schema.rb, and migrations.
Apparently there should be many changes in the spree application directory
structure and file contents from 1.2.4 to 2.0.0.
Before spree comes up with an ideal automated solution, what's the best way
to solve the problem now?
Create a new store, compare the change and modify directories/files one by
one?
Thanks.
