Export Existing Users/groups and important for Production Server

Export *.dat files: Go to WebLogic Console>Security Realms>myrealm>Migration Tab> Export Sub-Tab>Export Directory on Server: /u01/osbTempData and save

Setup CLASSPATH:

1. export MW_HOME=/u01/app/oracle/product/middleware

2. export DOMAIN_HOME=$MW_HOME/user_projects/domains/<domain_name> 

3. export CLASSPATH=$CLASSPATH:$MW_HOME/wlserver_10.3/server/lib/weblogic.jar

5. cd $DOMAIN_HOME/security

6. mv DefaultAuthenticatorInit.ldift DefaultAuthenticatorInit.ldift.old

Rename and backup the following LDAP directory:
