How can I move a table to another filegroup in MS SQL Server?

Question

I have SQL Server 2008 Ent and OLTP database with two big tables. How I can move these tables to another filegroup without service int

Answer 1

Partitioning is one solution, but you could "move" the clustered index to the new filegroup with no service interruption (subject to some conditions, see link below) using

CREATE CLUSTERED /*oops*/ INDEX ... WITH (DROP_EXISTING = ON, ONLINE = ON, ...) ON newfilegroup

The clustered index is the data and this is the same as moving filegroup.

Please see CREATE INDEX

This depends on if your primary key is clustered or not, which changes how we'd do it
