On the initial integration run all items/subitems listed on the source board will be automatically cloned to the master board.
Integration is scheduled and run every hour, so all new items or changes to the existing items will be synced not immediately, but once an hour.
If changes are made to the items that are already cloned, all those changes will be reflected on the master board within the next integration run.
If an item is manually deleted from the master board, but stays presented on the source board, it will be recreated on the master board within the next integration run.
NOTE: It’s very important not to change the format of links populated in Source Item URL and Parent Item URL fields, because these links are used by the system for item identification.
