Migration from JSF 1.2 to 2.0

[Avik Mazunder]

I have developed a project in JSF 1.2 + Richfaces 3.2.2 + jdk6

Now, I want to migrate it to JSF 2.0 + Richfaces 4 + jdk 7

I am using Eclipse Indigo IDE and jBoss 7.1.1 server. So, I do I begin? After some search I found out that I have to edit faces-config from

<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xi="http://www.w3.org/2001/XInclude"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

to

<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xi="http://www.w3.org/2001/XInclude"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">

and also removed the javax.faces.DEFAULT_SUFFIX from web.xml

I think I saw a migration guide in the RichFaces 4 docs. Bitter experience tells me that the change to the version ID in faces-config is essential, though.

Your biggest problem is that RF4 is sufficiently different from RF3 that it's on the scale of migrating Visual Basic 6 to Visual Basic.Net. A lot of grunt work.
