During a linear unmerge, a base object record is unmerged and taken out of the existing merge tree structure. Only the unmerged base object record itself comes out of the merge tree structure, and all base object records below it in the merge tree stay in the original merge tree.

Merge tree structures that are built during the merge process are flattened after a Batch Unmerge process is executed. A tree unmerge is not available after a batch unmerge call.
