(originally posted on the WebWork user forum)

I just finished migrating two applications from Webwork 2.2.4 to Struts 2.0.0 and thought I'd share what steps are involved in the process.

### DTDs namespaces

XWork was moved under ASF umbrella sometime ago, thus caused change in DOCTYPE, to be compliant with the current version use the latest version available here. Below is presented the wrong DTD:

The valid one should like this:

### Package names

Substitute `com.opensymphony.webwork` to `org.apache.struts2`.
Substitute `com.opensymphony.xwork` to `com.opensymphony.xwork2`.

### Configuration files

Rename `webwork.properties` to `struts.properties`.
Rename `xwork.xml` to `struts.xml`.

Change all occurrences of 'webwork' in `struts.properties` and `struts.xml` to 'struts'.
In `web.xml`, change `com.opensymphony.webwork.dispatcher.FilterDispatcher` to `org.apache.struts2.dispatcher.FilterDispatcher`.

### Converters

If you are using converters that subclass WebworkTypeConverter, rename the superclass to StrutsTypeConverter.

### JSP's

You have to change the taglib URI: `uri="/webwork"` to `uri="/struts-tags"`

Then you're done!
Well, maybe I've forgotten something but I'll guess you find that out when you try do compile and deploy your application...
