Explanation:
The following operations are performed by the AIA Migration Utility:
Detects the type of service, and depending on whether it is a BPEL process or an ESB process,
invokes the appropriate version of the SOA upgrade utility to perform the migration.
Updates AIAComponents references in WSDLs and XSDs to point to Oracle Metadata Services
(MDS) repository. (**)
Updates the AIAAsyncErrorHandlingProcess reference in bpel.xml to point to the AIA Foundation
Pack 11g Release 1 error handling service.
Updates domain-value map (DVM) and cross-reference (XREF) signatures in XSL files to point to
AIAComponents in MDS. This step takes care of updating references to template and function
calls in the XSL files used by the process.
Inserts annotations in composite.xml.(***):
Annotations play a significant role in the AIA lifecycle and governance in AIA Foundation Pack 11 g
Release 1. The AIA Migration Utility injects annotations (empty placeholders) into the migrated
composites.
Depending on whether a process is a Requester Application Business Connector Service (ABCS),
Enterprise Business Service (EBS), Provider ABCS, or Adapter service, appropriate annotations
are inserted into the composites. The utility uses the process.type variable in
AIAMigrationUtility.properties for this purpose.
As a post-migration task, you must populate appropriate annotation values into the skeletal
structure provided by the utility to be able to harvest AIA artifacts into Oracle Enterprise
Repository.
Note:The Oracle Application Integration Architecture (AIA) Migration Utility seamlessly migrates
AIA 2.4 and 2.5 BPEL and Enterprise Service Bus (ESB) services to AIA Foundation Pack 11 g
Release 1. The utility leverages the SOA upgrade utility to perform the bulk of the migration tasks

and automates most of the pre- and post-migration tasks.
