Convert a web application from ext1.1 to ext 4

[StutiAwasthi]

Hi all!

I am trying to covert a web application built using ext1.1 to ext4.
I am kinda new to ext. Need guidance for it. How long should it take to complete?
All suggestions are welcome.

i case you want to go from 1 to 4 i strongly recommend to completely rewrite the ext parts and get familiar with the new MVC and application architecture first.

take a look at the new docs:
http://docs.sencha.com/ext-js/4-0/

Take a look at Ext.data.Model (http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.Model) and the data package (http://docs.sencha.com/ext-js/4-0/#!/guide/data).
