1. If you have changed the LDAP Changelog location, but want to reset it to its original location, use dsconfig to reset it. The following command resets the LDAP changelog backend to <server-root>/db location. Remember to include the LDAP connection parameters (for example, host name, port, bindDN, bindPassword).
    $ bin/dsconfig set-backend-prop --backend-name changelog \ 
      --reset "db-directory"
  2. The server attempts to use whatever it finds in the configured location when it starts. If there is nothing there, it will create an empty database. If the LDAP changelog backend at the previous location is enabled at the time, stop the server, manually copy the database files to the new LDAP changelog location, and then restart the server.
