Migration from an AIA 2.4 or 2.5 production environment to an AIA 11g Release 1 environment is a carefully planned exercise. The methodology must be determined by the project team on site, taking into account actual requirements. The overall process flow is illustrated in Figure 15-1.
Use the following steps as general guidelines for your migration:
Set up an AIA Foundation Pack 11g Release 1 environment.
Set up a fresh SOA instance data store and AQ JMS queues.
Migrate Composite Application Validation System (CAVS) definitions and system registrations to the production system.
Migrate services and deploy the services to the new 11g production environment.
Upload AIA metadata to the Oracle Metadata Services (MDS) repository.
As a planned outage, suspend and stop all events and applications triggering the pushing of messages to the AIA 2.4 or 2.5 environment.
Allow all in-flight messages in the AIA 2.4 or 2.5 environment to complete.
Move cross-reference data from the 10g cross-reference database to the 11g cross-reference database.
Modify applications to divert messages to the new AIA Foundation Pack 11g Release 1 environment.
Restart the events and applications triggering the pushing of messages to the AIA Foundation Pack 11g Release 1 environment.
