You can migrate enterprise archive (EAR), Web archive (WAR), enterprise bean (EJB) JAR, application client JAR, resource adapter archive (RAR) files created with the Application Assembly Tool (AAT), Assembly Toolkit or a different tool to the Application Server Toolkit or Rational Web Developer.
This article assumes you have previously assembled code artifacts that you want to work with in an assembly tool such as the Application Server Toolkit (AST) or Rational Web Developer.
You can migrate EAR, WAR, enterprise bean JAR, application client
JAR, or RAR projects or files to an assembly tool using the J2EE Migration
wizard or by importing the files.
Optional: Migrate a project from J2EE 1.2 to 1.3 or 1.4, or from J2EE 1.3 to 1.4, using the J2EE Migration wizard. As part of the migration, you can migrate CMP 1.x beans to CMP 2.x beans.
The J2EE Migration wizard is similar to the earconvert batch utility or the File > ConvertEar option of the AAT.
In the Project Explorer view, right-click the enterprise application
project (EAR file) you want to migrate.
