Using the PartitionMergeUtility class, you can merge data from one or more partitions into a single target partition. Merging partitions is beneficial for simplifying a partitioned environment and for placing historical data into a single partition. When you merge partitions, the range of the target partition is set to the combined range of the merged partitions. The range value in the partition policy detail of the target partition is set to the highest range value of the merged partitions.
