The client configuration schema has changed between release 10.1.3.x and 11g Release 1. To migrate from release 10.1.3.x to 11g Release 1, use the utility shown in the code sample below:

java -classpath wsclient_extended.jar:bpm-services.jar 
 oracle.bpel.services.workflow.client.config.MigrateClientConfiguration 
original_file [new_file];

where original_file is a wf_client_config.xml file from 10.1.3.x and new_file is the optional name of the new configuration file. If a new name is not specified, the utility backs up the original configuration file and overwrites the wf_client_config.xml file.
