After spending a long time trying to upgrade from one SEAM version to another I found a "quick" way: 1 - Rename your eclipse project; 2 - With the new SEAM version, use SEAM-GEN to generate a project with the same name of the previous one; 3 - Copy the .xhtml pages, and source dir from the renamed project to the new one; 4 - Copy manually any changes made in components.xml and pages.xml to the new project It saves me a lot of time.
