[Option] /version [Description] 
For a selective merge, this option specifies the range that should be merged into the destination. For a catch-up merge, this parameter specifies the version before which all un-merged changes should be merged. For a selective merge, the version range denotes the beginning and end points of the set of changes to be merged. For example, if you attempt to merge version 4~6, the changesets 4, 5, and 6 are merged.
