How could I move a LOB segment of a partitioned table (DB 11.1)?

I have following table script:

CREATE TABLE COMMON.TEST_AAA2_ARH
(
  ID           INTEGER,
  TEKST        VARCHAR2(200 CHAR),
  UPDATESTAMP  DATE,
  OBJEKAT      CLOB
)
LOB (OBJEKAT) STORE AS (
  TABLESPACE COMMON_ARCHIVE
  ENABLE       STORAGE IN ROW
  CHUNK       8192
  RETENTION
  NOCACHE
  LOGGING)
TABLESPACE COMMON_ARCHIVE
LOGGING
PARTITION BY RANGE (UPDATESTAMP)
(  
  PARTITION P_201012 VALUES LESS THAN (TO_DATE(' 2011-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    LOGGING
    NOCOMPRESS 
    TABLESPACE COMMON_DATA
    LOB (OBJEKAT) STORE AS (
      TABLESPACE USERS
      ENABLE       STORAGE IN ROW
      CHUNK       8192
      PCTVERSION  10
      NOCACHE
      LOGGING),  
  PARTITION P_201101 VALUES LESS THAN (TO_DATE(' 2011-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
    LOGGING
    NOCOMPRESS 
    TABLESPACE COMMON_DATA
    LOB (OBJEKAT) STORE AS (
      TABLESPACE USERS
      ENABLE       STORAGE IN ROW
      CHUNK       8192
      PCTVERSION  10
      NOCACHE
      LOGGING),  
  PARTITION P_MAXVALUE VALUES LESS THAN (MAXVALUE)
    LOGGING
    NOCOMPRESS 
    TABLESPACE COMMON_ARCHIVE
    LOB (OBJEKAT) STORE AS (
      TABLESPACE COMMON_ARCHIVE
      ENABLE       STORAGE IN ROW
      CHUNK       8192
      PCTVERSION  10
      NOCACHE
      LOGGING)
)
NOCOMPRESS 
NOCACHE
NOPARALLEL
MONITORING;

and I would like to move lob segment from USERS tablespace to another one..

tnx
