Moving an IOT

Question

How do you move an index organized table? I tried the following:
SQL> alter table WKSYS.SYS_IOT_OVER_27912 move tablespace sysaux;
alter table WKSYS.SYS_IOT_OVER_27912 move tablespace sysaux
ERROR at line 1:
ORA-25191: cannot reference overflow table of an index-organized table
[pre]
Then, after searching for a solution, I tried the following:
[pre]
SQL> alter table WKSYS.SYS_IOT_OVER_27796 move tablespace sysaux overflow tablespace sysaux;
alter table WKSYS.SYS_IOT_OVER_27796 move tablespace sysaux overflow tablespace sysaux
ERROR at line 1:
ORA-01735: invalid ALTER TABLE optionNo luck.
Next question:
Is there a way around this one or should I extract the DDL for the index and recreate it?
SQL> alter index CTXSYS.SYS_IOT_TOP_51146 rebuild tablespace sysaux;
alter index CTXSYS.SYS_IOT_TOP_51146 rebuild tablespace sysaux
ERROR at line 1:
ORA-28650: Primary index on an IOT cannot be rebuiltThanks

Hi,
The IOT overflow must be moved.
SQL> select table_name from dba_tables
2  where iot_type = 'IOT_OVERFLOW'
3  and tablespace_name = 'TS1';
TABLE_NAME
SYS_IOT_OVER_12214
SQL> select object_name, owner from dba_objects
2where object_id in
3  (select replace(table_name,'SYS_IOT_OVER_')
4  from dba_tables
5  where iot_type = 'IOT_OVERFLOW'
6  and tablespace_name = 'TS1');
OBJECT_NAME            OWNER
T1_IOT                 TEST
SQL> -- Move the overflow segment to another
tablespace.
SQL> alter table t1_iot
2  move
3  overflow tablespace users;
SQL> select table_name, tablespace_name, iot_type
2  from user_tables;
TABLE_NAME                    TABLESPACE_NAME
IOT_TYPE
SYS_IOT_OVER_12219            USERS
IOT_OVERFLOW
T1_IOT      IOT
Hi,
this method didn't work for me
select table_name from dba_tables 
  where iot_type = 'IOT_OVERFLOW' 
    and tablespace_name = 'EXAMPLE';
select object_name, owner from dba_objects 
where object_id in 
  (select replace(table_name,'SYS_IOT_OVER_') 
    from dba_tables 
      where iot_type = 'IOT_OVERFLOW' 
        and tablespace_name = 'EXAMPLE'); 
OBJECT_NAME                    OWNER
AQ$_ORDERS_QUEUETABLE_G        IX
AQ$_STREAMS_QUEUE_TABLE_G      IX
SQL> alter table ix.AQ$_ORDERS_QUEUETABLE_G    move    overflow tablespace users;
alter table ix.AQ$_ORDERS_QUEUETABLE_G    move    overflow tablespace users
ERROR at line 1:
