AK,

		hi, row chaining is because the big row(row length is bigger than the block size), while row migration is because of small pctfree and updated rows.
		So, just look at the length of the rows. If chained rows, no way(unless you use larger block size and the row does not contains really long column like long/long row data type), if migrated rows, you can move the table to repair the migrated rows.
	Good luck
