Rob Allen has a quick post about his conversion of his schema manager over from the Zend Framework version 1 to the upcoming version 2 - a simple task, as it turns out.
I've started playing with the development versions of ZF 2.0 and one of the first things I thought I'd do was to port Akrabat_Db_Schema_Manager. It turned out to be reasonably easy. All I needed to do was rework my use of ZF components to use the new ZF2 ones. Whilst I was at it, I also converted it to use namespaces. I also had to reorganise the http://github.com/akrabat/Akrabat library so that I could have ZF1 and ZF2 code in it.
He includes "before" and "after" snippets of code to help illustrate the example. He had to change up things just a bit to handle the namespaces because of naming issues (a class named "Abstract" isn't allowed). If you want to see more of the updated code, you can check out his account on github with the changes.
