Estoy trabajando en la migración de datos de WL 5.0.6.2 a 6.2. Mientras lo hacía, encontré problemas al ejecutar la herramienta de migración de datos.

Antecedentes: Enfoque: exportamos la tabla WRKLGHT de 5062 DB a una base de datos intermedia para la migración de datos, por lo que la base de datos en ejecución no se ve afectada.

DBs:
   1. schema: proj
     its storing 5062 runtime data, upgrade-worklight-506-60-oracle.sql, upgrade-worklight-60-61-oracle.sql upgrade sql are executed.
   2. schema: proj6
     its blank DB at first, "create-worklightadmin-oracle.sql"  is executed to prepare WLADMIN tables.

WL Project existing:
    1. wlProj 
        its the app running on 5062 WL server
    2. wlProj6
        its the target project running on 6.2 WL, and data will be migrated to be used by this project

Steps:
1. recreate proj6 schema
    1.1 SQLPlus -> connect as SYSTEM -> "drop user proj6 cascade"
    1.2. -> "create user proj6 identified by {password}" -> "grant all privileges to proj6"

2. execute "create-worklightadmin-oracle.sql" on proj6 schema
     2.1 SQLDeveloper -> connect as user proj6
     2.2 run @"{ WL server install dir}/databases/create-worklightadmin-oracle.sql";
     2.3 commit

3. Open cmd and run the following command
    java -cp ojdbc6.jar;worklight-ant-deployer.jar com.ibm.worklight.config.dbmigration62.MigrationTool -p /wlProj   -sourceurl jdbc:oracle:thin:@//192.168.0.**:1521/xe   -sourcedriver oracle.jdbc.driver.OracleDriver   -sourceuser proj   -sourcepassword ***  -targeturl jdbc:oracle:thin:@//192.168.0.***:1521/xe   -targetdriver oracle.jdbc.driver.OracleDriver   -targetuser proj6   -targetpassword *** 2>out.txt

'migrando wlProj- {ios, android}' y 'migrando el registro de datos de acceso para wlProj -.....' se muestran en cmd.

Y enout.txt, se muestra el siguiente error.
