Redmine

1 how to from 2.0.3.1 to 2.4.1.1 only redmine

(I download redmine2.4.1.1.zip, and in cmd run "rake db:migrate RAILS_ENV=production",
but is error:"rake aborted!
No Rakefile found")

2 if i install "bitnami-redmine-2.4.1-1-windows-installer.exe" in new server pc, how i can get redmine 2.0.3.1's old data into 2.4.1.1?

thanks! best you!

我如何升级现有的2.0.3.1到2.4.1.1？
2.0.3.1是在window2003下安装的bitnami集成工具包。

1、直接把现在的redmine程序升级到最新。

2、如果我在新服务器上安装了集成工具"bitnami-redmine-2.4.1-1-windows-installer.exe"，如何把2.0.3.1的数据库导过来？

谢谢！
