Go to Item Folders, Right Click on Master JCM, select New Folder, Tick the "Add Sub Folders Too" box, click "Browse", open the Master folder and select the folder called Metric_2_31_072, click Select, Give it a name like New Patterns and click OK.
We have to include all Patterns as not everyone has updated on a regular basis, take what you need out of the folders and delete them when finished.
