If a new filegroup is created on a new disk drive, is there a way to migrate
a specific clustered index to the new filegroup?
Regards,

I'm having trouble with the syntax. Index is created and dropped with
ALTER TABLE [dbo].[tSupplierItemXrefs] ADD CONSTRAINT
[PK_tSupplierItemXrefs] PRIMARY KEY CLUSTERED
(
[SupplierXrefKey] ASC
) ON [PRIMARY]
IF EXISTS (SELECT * FROM dbo.sysindexes WHERE id =
OBJECT_ID(N'[dbo].[tSupplierItemXrefs]') AND name = N'PK_tSupplierItemXrefs')
ALTER TABLE [dbo].[tSupplierItemXrefs] DROP CONSTRAINT [PK_tSupplierItemXrefs]
WHEN I RUN:
CREATE CLUSTERED INDEX PK_tSupplierItemXRefs ON tSupplierItemXrefs
(SupplierXrefKey) WITH DROP_EXISTING ON "DDRIVE"
I get an error:
Server: Msg 1907, Level 16, State 1, Line 1
Cannot re-create index 'PK_tSupplierItemXRefs'. The new index definition
does not match the constraint being enforced by the existing index.
DDRIVE is the additional filegroup I created for this table and which exists
on a drive other than the primary filegroup drive.
