Kie Workbench Migration Tool
============================

1) PROJECT STRUCTURE MIGRATION (Moves old project structure to new modules structure)
2) SYSTEM CONFIGURATION DIRECTORY STRUCTURE MIGRATION (Moves old system configuration directory structure to the new one)
3) FORMS MIGRATION (Moves old jBPM Form Modeler forms into the new Forms format.)
4) POMS MIGRATION (Migrates pom.xml files to format compatible with KIE Maven build.)
5) SYSTEM TO SPACE CONFIGURATION REPOSITORY MIGRATION (Moves spaces and repositories metadata to each space configuration repository)
6) ALL
7) EXIT

Choose one option [1-7]: 2
