-Import a visualization and dashboard with an index pattern for the visualization reference that doesn't exist:
+This result indicates that the import was not successful because the index pattern, visualization, and dashboard each resulted in a conflict error:
+
+* An index pattern with the same ID already exists, so this resulted in a conflict error. This can be resolved by overwriting the existing
+object, or skipping this object entirely.
+
+* A visualization with a different ID but the same "origin" already exists, so this resulted in a conflict error as well. The
+`destinationId` field describes to the other visualization which caused this conflict. This behavior was added to ensure that new objects
+which can be shared between <<xpack-spaces,spaces>> behave in a similar way as legacy non-shareable objects. When a shareable object is
+exported and then imported into a new space, it retains its origin so that it conflicts will be encountered as expected. This can be
+resolved by overwriting the specified destination object, or skipping this object entirely.
+
+* Two canvases with different IDs but the same "origin" already exist, so this resulted in an ambiguous conflict error. The `destinations`
+array describes to the other canvases which caused this conflict. When a shareable object is exported and then imported into a new space,
+and is _then_ shared to another space where an object of the same origin exists, this situation may occur. This can be resolved by picking
+one of the destination objects to overwrite, or skipping this object entirely.
+
+These errors need to be addressed using the <<saved-objects-api-resolve-import-errors-example-1,Resolve import errors API>>.
