How to move Non-Clustered indexes from one Filegroup to another Filegroup within a database

Normally, Maintening the Indexes on different filegroup is better performance. But there is some limitations..
1. Unique Index
2. Clustered Index
3. Primary Key with Clustered or Non-Clustered Index can not / may not be moved to another filegroup.

Moving Non-Clustered Indexes from PRIMARY filegroup to Secondary Filegroup.

Steps to be followed:
1. Create a new filegroup named : Secondary
2. Add data files to the Filegroup.
3. Execute the script given below

DECLARE @FGFrom	VARCHAR(50), 
	@FGTo	VARCHAR(50)

SELECT	@FGFrom = 'PRIMARY',
	@FGTo	= 'Secondary'

BEGIN TRY
	BEGIN TRAN
		CREATE TABLE #NonClusteredIndex
		(
		Id	INT IDENTITY(1,1),
		NCI	VARCHAR(MAX));

		DECLARE @intIndex			INT,
			@intIndexCount		INT,
			@NCIScript			VARCHAR(MAX)

		SELECT @intIndex = 1

		INSERT #NonClusteredIndex(NCI)
		SELECT 'CREATE NONCLUSTERED INDEX ' + I.name + ' ON ' + OBJECT_NAME(i.[object_id]) + '(' + index_col(OBJECT_NAME(i.[object_id]),I.index_id,1) + ') WITH (DROP_EXISTING = ON,ONLINE = ON) ON ' + @FGTo
		FROM sys.indexes i JOIN sys.data_spaces s
		ON(i.data_space_id = s.data_space_id)
		JOIN sys.objects o ON(o.[object_id] = i.[object_id])
		WHERE o.[type] ='U'
		AND i.type_desc ='NONCLUSTERED' 
		AND	I.is_unique = 0
		AND S.name = @FGFrom
		
		SELECT @intIndexCount = @@ROWCOUNT

		WHILE(@intIndex <= @intIndexCount)
		BEGIN
			SELECT @NCIScript = NCI FROM #NonClusteredIndex WHERE ID = @intIndex
			EXEC(@NCIScript)
			SELECT @intIndex = @intIndex + 1
		END

		DROP TABLE #NonClusteredIndex
		COMMIT
END TRY
BEGIN CATCH
		DECLARE @ErrMessage	NVARCHAR(MAX)
		SELECT @ErrMessage = ERROR_MESSAGE()
		RAISERROR(@ErrMessage,16,1)
		ROLLBACK
END CATCH

You can changes the script as yours...
