NOTE: Prior implementations of CAD 8.0, 8.5, and 9.0 supported the
use of flat files or Microsoft SQL Server as the data store. As a matter
of policy, effective immediately with release 9.0(3), all customers with
new deployments of any version of Cisco Agent Desktop must use
SQL Server as the data store, and not flat files. The rationale behind
this policy is that deployments with a fully replicated SQL Server
database experience a more complete feature set and better
performance and stability.

Customers who are upgrading to CAD 9.0(3) from a previous version of CAD
that was run on Windows Server 2003 (CAD 7.5, 7.6, 8.0, 8.5(1), and 8.5(2a))
must migrate to SQL Server 2008 R2 as the data store.

must migrate to SQL Server 2008 R2 as the data store.
Customers who used flat files with CAD 8.5(4) and CAD 9.0(1a) running on
Windows Server 2008 R2 can continue to use flat files when upgrading to
CAD 9.0(3), but are also encouraged to migrate to SQL Server 2008 R2. CAD
documentation outlines the caveats associated with the use of flat files,
including loss of functionality during fail over situations that might be cause
by several reasons, network issues being the most common. Cisco Support
and TAC reserves the right to request a migration to SQL Server 2008 R2 as a
resolution plan.
