Hi All,

I have an application that is currently in 3.0.2 version. I need to upgrade the ExtJs version to 4.1.3

Can anyone please provide some pointers to resolve this? or in order to migrate it

Here is a blog that will help:

My personal recommendation is to use Sencha Cmd to generate the app and then move your app over to MVC to gain the full benefit of Ext4 .. yes, a re-write ;)

If this is not an option, the guide above should get you going just fine.
