Index.DropAndMove Method (String)
Drops a clustered index and moves the underlying table data to the specified filegroup.
Assembly: Microsoft.SqlServer.Smo (in Microsoft.SqlServer.Smo.dll)
The OnlineIndexOperation and MaximumDegreeOfParallelism properties affect this method. The parent Table object needs to be refreshed by calling the Refresh method to reflect the latest state, because this will not be updated by this method automatically.
Indexes based on the UserDefinedTableType object cannot be modified and running this method will generate an exception.
