Migrating from Sybase to SQL Server

(Page 1 of 4 )

Projects involving database migration are common. In this article Sayed shares his experiences in migrating from Sybase to SQL Server...I was involved in a recent project to migrate a Sybase database to Microsoft SQL Server 2000. The experience I gained by working on this project has led me to write this article to show Sybase database administrators (DBA’s) and managers the steps that should be followed to migrate from a Sybase database to an SQL Server 2000 database.

Although some differences will be quite noticeable, such as a Sybase stored procedure that refuses to compile in SQL Server, other differences are much more subtle. It will be necessary to heavily test the behavior and resultsets of all programming logic in script files and stored procedures prior to completing the conversion.

In the following section I provide a set of core differences between the two databases that must be explored during the critical planning stage.
