Today I feel very lucky and I decided to migrate all my application that I build on the Advertisement Agenda project and may be I can find some easy ways of migration. This is the first time I intend to migrate any older version of a framework in the middle of a project. Let’s see what is waiting for e .
By the way, there is a complete tutorial and an easy way of doing the migration with a compatibility tool that you should install. But I want to have complete new start with Ext JS 4. And why I need to migrate is the API that I use is not compatible with the application I’m developing. It is really become a confusion for me. Here I go..
Step By Step Migration Plan
- Backup Project Files for later needs
- Download new release of Ext JS from http://www.sencha.com/products/extjs/download/
- Just change the base ext file path to the new one.
- Try it out.
- If there has been a problem, try to figure out what is it and solve the problem.
- Continue to the 4th step until there is no problem.
- If I still came up nowhere, start to build a complete new application.
So, how did it go? I did the first 4 steps and jump to the 7th one . It looks like I need a complete new application.
Here what it is! There is not enough documentation about the steps to build an application from start. I decided watch those videos first:
I must say, I’m stucked! I’ll go through examples, that will do.
