Upgrading cordova of existing project

I already have a Cordova project built on older versions(2.3.0). Now I want to upgrade it to Cordova 3.3.1. I installed Cordova 3.3.1-0.1.2 using npm

npm install -g cordova@3.3.1-0.1.2

Then I am trying to upgrade my project with command

update_cordova_subproject

I don't see that command file available in the bin folder of Cordova installed location. In my case it is C:\Users\KAVVA01\AppData\Roaming\npm\node_modules\cordova\bin.

I can see only cordova.cmd in that. Where can I find "update_cordova_subproject" command file.

Any thoughts?

update_cordova_subproject will not be available if your Cordova version is older than 3.0. There is no direct way to upgrade older versions < 3.0.
