This document discusses porting a commercial Eclipse RCP application to Eclipse 4.x. It covers the RCP and Eclipse 4.x architectures, different migration paths including recompiling with a compatibility layer and fully migrating to the 4.x APIs, issues with a mixed mode migration, and pros and cons of migration. A demo is shown of a sample application with a migrated editor and legacy views.
