11. Transition Plan ● Sequester Reference Applications ● Configure Them as Nightly Builds ● Move to Git ● Do three clean up releases ● Split into topic branches ● Insert code review infrastructure ● Flow towards Master for ITKv4 Beta ● Generate Migration Guide ● As we go

12. Securing Reference Applications ● ITK Testing Directory ● InsightApplications ● Slicer 3.6 ● ITK-SNAP ● GoFigure ● OrfeoToolbox ● BRAINS ● IGSTK ● MITK (Heidelberg) ● ANTs ● LSTK ● V3D Plugins ● FARSIGHT ● Elastix ● VesselTK ● MedINRIA

13. Securing Reference Applications ● For all these applications: ● Their release versions will be cloned in Git ● They will be build Nightly against the transitioning version of ITK ● When a change in ITK breaks any of these applications, a “Migration Report” will be filled out, and the application will be fixed.

14. Migration Report ● Will include: ● What Changed in ITK ● Why was this changed ? (justification) ● Compilation errors it produced in the apps. ● Patch that was used for fixing the apps. ● It will serve as a database of compilation errors and their solutions.
