This section describes the steps required to migrate either a DB2
Common Server Version 2.x, a Database Server Version 4.x, or a
DB2 Universal Database Version 5.x single-partition database system to
a Version 6 partitioned database system. It also includes information
on how to update a Version 6 single-partition database system to the Version 6
multipartition format.
|
| The migration process for Database Server Version 4 is identical to that used for DB2 Common Server Version 2. Whenever Version 2 is mentioned in this section, the same information also applies to Version 4. |
When you migrate from a Version 5.x database system to a DB2 Enterprise - Extended Edition Version 6 database system, depending on the installation option you choose, the setup program will migrate all instances to the Version 6 multipartition or single-partition format. If you are migrating a database with populated tables, refer to the Administration Guide for descriptions of how to add database partition servers to a system and redistribute data across database partitions.
After you install DB2 Enterprise - Extended Edition, any databases that you created with earlier versions of DB2 will not automatically work with the new version of DB2. You must follow the steps in this section to migrate your instances and databases.
If you are migrating a DB2 Version 2.x database to DB2 Enterprise -
Extended Edition, the database is relocated from the
\instance_name directory to the
\instance_name\NODE0000 directory. A node is
created with a default name of NODE0000.
