This guide presents information on the most common issues encountered and possible solutions for migrating Sybase databases to SQL Server. The guide focuses on procedures for transferring the items in a Sybase database and on redirecting and redeploying DB-Library and CT-Library applications to use a migrated database. Depending on the specific technologies used to host these client applications, at least three options are available for reconfiguring them: 1) Client applications can remain in their existing environment and be redirected to SQL Server. 2) Client applications previously executing under UNIX can be redeployed to the computer running Microsoft Windows®, hosted in the Microsoft Windows Services for UNIX (SFU) environment, and then redirected to SQL Server. 3) Client applications can be fully ported to the Microsoft Windows platform and rewritten to take advantage of Microsoft technologies and APIs.
