Migrating and importing index data

Index migration is the process by which IBM® Content Manager OnDemand moves index data from the database to archive storage. This process optimizes database storage space while allowing you to maintain index data for a very long time. You typically migrate index data after users no longer need to access the information, but for legal or other business requirements, you still need to maintain the data for some number of years. If a user queries index data that has been migrated, an administrator must import a copy of the migrated table into the database. After maintaining the imported table in the database for a specified number of days, Content Manager OnDemand deletes it from the database.

This section provides information about importing index data into the database, including what happens when a user queries for migrated data, how to import the index table or tables required by the query, and what happens after you import a table into the database.

IBM assumes that an experienced Content Manager OnDemand administrator will use the information provided in this section. If you have questions about any of the topics in this section or if you would like help configuring your system to support migrating and importing of index data, contact the IBM support center.

In general, migrating index data is not recommended.
