JDevelopr 10g to 11g. It's a long way to migration

Today i tried migrating a simple project from JDeveloper 10g (10.1.3.4) to 11g (11.1.1.0.1) )and the results are mostly disappointing.

A picture is a thousand words.

This is how the application looks today.	... and here is how it ended up after migration......

Just for the shake of complicity, I have to report the following :

• Migration finished without any exceptions being thrown at the console. The only warning message that appears when opening the project is :

  Mar 30, 2009 9:43:18 AM oracle.jdevimpl.webapp.taglib.JDevTaglibUtils _parseFail
  WARNING: Invalid TLD Location, TldUtils parse failed for URL : jar:file:/home/oracle/jdeveloper/mywork/AS400-Materials/ViewController/opt/oracle/Middleware/jdeveloper/jlib/adf-faces-databinding-rt.jar!/META-INF/databinding.tld
      

• Although attribute labels are not shown in the search page, the Attribute properties page displays them correctly.
  
• The initial JSF navigation diagram, does not display any graphic, despite the fact that I see no error ether on the message window or the console.
  

I feel like I want to complain to somebody, but I am not sure to whom.
