Back up Informix® after migrating to the new version

Use a backup and restore tool (ON-Bar or ontape) to make a level-0 backup of the new database server. Do not overwrite the tapes that contain the final backup of the old database server.

For more information, see the IBM® Informix Backup and Restore Guide.
Important: Do not restore the backed up logical-log files from your old database server for your new database server.
