Does SQL Server move records between partitions when updating the partition key column?

If I run an UPDATE query on a table which is partitioned by the column I am updating - will the records be moved to another partition?

ie. I have a table where Historical bit column marks whether a particular record should go to Partition1 (=0) or Partition2 (=1). Now, I update a record in that table and change the Historical column value from 0 to 1. What happens with that record?

It will move to the other partition.

Thanks,|||Thank you. That's the kind of behavior I was looking for.
