Migrating the DBB server

If you are upgrading the DBB server from a previous release, the configuration from the old server must be merged into the new server configuration and the database must be migrated before starting the new server.

Procedure

1. Review server configuration changes made to the original installation. Merge those changes into the new installation. Changes may include ports and user registry customizations and database configurations.

2. Backup the current database following established and verified procedures for your database.

3. Run the appropriate upgrade script located in /wlp/usr/servers/dbb/DDL.

   Notes:

   • Not every version has its corresponding upgrade script. Check directory /wlp/usr/servers/dbb/DDL for all available upgrade scripts. For example, there is no upgrade script for V1.0.2.
   • You must run the upgrade scripts from your currently installed version up to the new version that you are upgrading to. For example, if you are upgrading from version 1.0 to 1.0.3, you must run the upgrade scripts for V1.0.1 and V1.0.3.

4. Review the output and verify that all database commands run successfully.

5. If it is necessary to roll back changes to the database, restore the database from the backup.
