Migrating to BIRT iHub
When migrating to BIRT iHub, the administrator first installs BIRT iHub in a stand‑alone, side-by-side configuration with an existing BIRT iServer Release 11 system. After installation, the administrator reconfigures BIRT iHub to use the existing BIRT iServer relational database management system (RDBMS) that contains the system and Encyclopedia volume metadata and related data stored on disk.
The administrator installs and migrates to BIRT iHub by performing the following tasks:
Shuts down the BIRT iServer Release 11 system and, if using the embedded out-of-the-box (OOTB) PostgreSQL RDBMS, shuts down the Windows Actuate 11 PostgreSQL for BIRT iServer service. It is not necessary to shut down the service for an alternative RDBMS, such as DB2, Microsoft SQL Server, Oracle, or a pre-existing PostgreSQL system.
Installs a stand‑alone BIRT iHub System that uses the embedded OOTB PostgreSQL RDBMS, then shuts down the BIRT iHub System and PostgreSQL RDBMS.
Backs up the existing BIRT iServer Release 11 System to safeguard against failure, including all metadata, data, and necessary configuration files.
Performs the manual operations necessary to reconfigure BIRT iHub to use the existing BIRT iServer RDBMS that contains the system and Encyclopedia volume metadata and related data stored on disk.
If migrating from a BIRT iServer installation earlier than Release 11 Service Pack 4, such as Release 11 Service Pack 1, 2, or 3, runs the Ant script, a11Upgrade.xml, to upgrade the Encyclopedia volume schema before restarting BIRT iHub.
Restarts BIRT iHub System.
When migrating to BIRT iHub from an earlier iServer installation, such as Release 10 Service Pack 1, the administrator must first upgrade to Release 11, then migrate to iHub.
