Appendix A. Migration

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:

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.

Note that migration can take a considerable amount of time. While migration is running, no changes should be made to the user tables.
