Unanswered: Migration to extjs 4 from extjs 2
I have a problem with migrating the existing extjs 2 or 3 to extjs 4. Could some one help me out in this.
We have used extjs 4 and trying to convert my code into it.
But, none of the extjs 2 controls are loading while converting. Except the aspx master page.
Need someone to help us in this regard ASAP.

ExtJS 2.x to 4.x is not an upgrade, it's basically a re-write. You will need to prototype each piece of your app to see how the framework has changed (which is heaps).Lead Trainer / Sencha Specialist

Work Ahead my dear
You have to completely recreate the application from extjs2.You have to learn extjs 4 before doing the migration as ext4 is completely different from Ext2.There is no way to simply migrate from ext2.All the Best.....
