DB2 Net Search Extender Version 8.1.x has been extensively altered to include the search interface and functions of DB2 Text Information Extender Version 7.2. Accordingly, there are three migration options:
If you are migrating from DB2 Version 7.2 and Text Information Extender Version 7.2, you must begin with the migration of the DB2 instance and the instance databases. Refer to the appropriate DB2 documentation for the correct syntax and usage of the DB2 commands, such as db2imigr which you must use to migrate the DB2 instance from version 7 to version 8, and db2 migrate db <db name> which you must use to migrate the instance databases.
The DB2 Net Search Extender migration procedure is called db2extmdb and returns messages in English. If an error occurs during migration, attempt to fix the error, and call db2extmdb again.
db2extmdb collects all db2ext administration information relevant to migration in a new table called DB2EXT.TMIGRATION, where each text index is represented by a single row in the table. This migration information table persists until the database has been successfully migrated. You are not allowed to drop this table.
During text index migration, processing differs depending on the state of the log table, and the availability of the index files:
Note that migration can take a considerable amount of time. While migration is running, no changes should be made to the user tables.
