Enhance your Sencha ExtJs from version 2.2.3 to the latest version 6

I find myself at a crossroads, having inherited a .Net Web Forms application that was developed in 2017 and utilizes Ext2JS version 2.2.3 from 2007. Unfortunately, this app is failing all security scans due to the outdated version of Ext2JS. I am in need of assistance in upgrading it to either the latest version or at least ExtJS 6.0. Is there any documentation available that outlines the changes between versions? As someone with no prior knowledge of ExtJS, any guidance on this matter would be greatly appreciated.

Answer №1

As someone who recently made the transition from ExtJS 6.2.5 to 6.6.0, I can attest to the challenges that come with a migration spanning 4 MAJOR VERSIONS...

Before diving into a migration project, it's crucial to assess the complexity of your application and weigh the cost/impact. Consider whether starting fresh with the 6.6 framework would be a more efficient approach.

For those new to ExtJS, bear in mind that this powerful framework demands a solid understanding for successful migrations, as you'll likely need to modify numerous xtypes (objects).

If after careful consideration a migration still seems like the best path forward, check out these helpful resources:

(This link specifically addresses moving from version 3.4 to 6.6)

Best of luck on your migration journey!
