Migrating a DB2 database system

After you install DB2 Version 9.5 for Linux, UNIX, and Windows on a system where DB2 UDB Version 8 or later is installed, all the instances and databases must be migrated to be able to run them under DB2 Version 9.5. If you have DB2 UDB Version 7 or earlier installed, you have to migrate to DB2 UDB Version 8 first.

For Windows operating systems: When you install DB2 Version 9.5, you can choose to migrate an existing DB2 UDB Version 8 or Version 9 automatically as part of the installation. You can also migrate your instances manually after installation. You need to migrate all the databases manually after you migrate your instances.

Migration from other database management systems

You can migrate your databases and applications to a DB2 database system from other database management systems such as Oracle, Sybase, or Microsoft SQL Server. You need to consider several factors such as converting your database objects, moving the actual data, and converting SQL statements and interface calls in your applications. This is a complex process that requires an assessment to determine what the migration entails and requires the creation of a porting plan.
