You can compare one pipeline with another. Pipeline comparison works across projects and project spaces. You can compare any pipeline that you have permission to view. You can also compare two versions of the same pipeline.
Pipelines are compared based on:
the type of Snap it is and its neighboring Snaps.
if unmatched, then Snaps are compared by there type only.
if a Snap is in the source pipeline, but not in the target, it is considered deleted.
if a Snap is in the target pipeline, but not in the source, it is considered added.
visual position is not relevant.
The Label (name) of the Snap is not considered in the comparison. If you have multiple of the same type of Snap within your pipelines, they may be compared with a different version of the Snap than you are expecting.
