Redmine

Hello,

I'm front of strange thing: I moved a redmine instance on new server. Following these steps:

1. Install redmine on new server (using this)
2. Copy from old instance:

• database
• files
• theme

3. Follow upgrade howto

Execution of bundle exec rake db:migrate RAILS_ENV=production look fine:

# bundle exec rake db:migrate RAILS_ENV=production --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
** Invoke db:_dump (first_time)
** Execute db:_dump
** Invoke db:schema:dump (first_time)
** Invoke environment 
** Invoke db:load_config 
** Execute db:schema:dump

My new instance works perfect. But seems not upgraded. On page /admin/info i can read:

Redmine version 2.5.2.devel

And debian installed version is:

redmine:
  Installed: 3.0~20140825-8~deb8u3
