There are a lot of benefits to be reaped by migrating a BPM 10g project to 12c. For one, Oracle BPM 12c is built on a Service Component Architecture (SCA) runtime. SCA is an industry standard architecture that provides a model for composing applications that follow SOA principles, like component reuse, OOTB error handling and transaction management, and flexible development to name a few.
With the introduction of Oracle BPM Suite 12c (12.1.3), one of the key features introduced is a migration path for Oracle BPM 10g projects to 12c. Such a feature was not available in 11g and there was little to no hope for BPM 10g projects to be migrated to 11g. That hope has come alive with the introduction of 12c and so I decided to give it a shot. Below I have listed the steps to follow to do a 10g to 12c migration and summarized by findings.
1) Install Oracle BPM Suite 12c
First off, download the Oracle BPM Suite 12c quick start installer from Oracle’s website here. This installer includes JDeveloper 12c with SOA and BPM extensions. The installer also includes the migration utility, which is an ANT task.
The migration utility readme.txt recommends to use ANT version 1.8.4.
The migration utility can be found under $JDEV_HOME\soa\plugins\jdeveloper\bpm. The build.xml file has all the ANT tasks. The ANT task for the migration from 10g to 12c is “migrate10-12”, where source is the folder location of the 10g project and target is the folder location where the 12c project export will be created. Replace source and target appropriately and execute the below command.
ant migrate10-12 -DprojectLocation=source -Ddestination=target
Once the ANT task execution completes successfully, it creates the 12c project export in the target folder specified. This folder contains the following:
To import the exported version of the 12c project into JDeveloper, open the 12c JDeveloper. Create a BPM Application. Go to File -> Import -> Import BPM Project. Browse to the target folder and select the .exp file. This is a list of some of the artifact mappings: Read the complete article here.
