Behavior of Moving Synced Issues to Another Project
This article explains what happens when you move a work item that is synced with Backbone to a different project.
Default behavior
When you move the work item to another project, the following will happen:
Backbone will not throw an error (i.e work item is missing)
Backbone will synchronize changes made on the issue which was not moved to the work item which was moved
You can unlink the work items/issues if you don't want the changes to be synced anymore
Backbone will not synchronize changes made on the issue which was moved
If you are moving a work item to a project with a synchronization: Backbone will also sync the moved work item to a new work item and keep those two in sync according to the new synchronization. Please note that sync panel info might be outdated after moving a work item if the steps to clear the sync panel are not followed.
