Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Installation Guide

MS SQL Server 2000 is a separate product that is available from Cisco. If you 
want to install MS SQL Server 2000, make sure that you obtain the MS SQL 
Server 2000 disk and the MS SQL Server 2000 for Cisco Customer Response 
Solutions Resources Card.

Cisco CRS does not support MS SQL Server 2000 for use with Cisco CRS in a 
deployment in which Cisco CRS components and Cisco Unified Communications 
Manager reside on the same server.

If you do not install MS SQL Server 2000 when you upgrade to Cisco CRS 6.0 
and your existing databases are too large to migrate, you may not be able to access 
all of your historical data when the upgrade completes. You can later retrieve 
some or all of the data by upgrading to MS SQL Server 2000 and then performing 
the Cisco 3.5(x) data migration procedure from the Cisco CRS Administration DS 
Control Center-HDS3x page. The amount of data that you will be able to retrieve 
depends on the size of the hard disk on which the database is stored.

You must use MS SQL Server 2000 if your Cisco CRS deployment includes high 
availability.

 shows the size of the Cisco CRS db_cra and db_cra_repository 

databases. As shown in this table, the size of these databases depends on the size 
of the hard disk on which the databases are stored, whether you are using 
MSDE 2000 or MS SQL Server 2000, and how you deploy Cisco CRS if you use 
MS SQL Server 2000.
