Migration from the older version of the JHeadStart to the newer version

Hi ALL,
i want to migrate an application form the older version of the JHeadStart (10.1.3) to the newest version (10.1.3.2 )
is there any things i must take care of it ??
as when i opened the application in the new JHeadStart and try to run the application definition i got java.lang.NullPointerException ???????????

In the default templates, a revision history lists the modifications made in new releases. If you know what functionality you changed compared to the old default template, you can apply that same change to the new default template.
If you use a Version Control System like CVS or Subversion, this is relatively easy. See the JHeadstart Blog post about Subversion at http://blogs.oracle.com/jheadstart/2007/02/20#a138, it includes a screen shot of how to see the changes between the old and new default templates.
See also the 2nd suggestion in section 4.7.2 of the JHeadstart Developer's Guide.
Hope this helps,
