I have created one Sencha Touch MVC application in 1.1. Now with release of sencha touch 2.0, I want to upgrade MVC application to sencha touch newer version. Can I do this? or how hard it is?
Of course you can do it... I don't really think it's too hard but I would actually create a new folder for the ST2 version and build it up from scratch using the code from the ST1 version as a reference. Instead of Ext.dispatch, in your controller, this.control is a replacement.
