unable upgrade 11.2.0.3.0 to 18c : workspace manager ORA-20000

Hi to all,

We are running on 11.2.0.3 in a Linux el7uek and we are planning to upgrade from 11.2.0.3.0 to 18C but we are facing error:

ORA-20000: All versioned table must have a 'VERSIONED' status before upgrading.

but all tables are versioned:

SQL> select table_name, owner, disabling_ver from wmsys.wm$versioned_tables;

TABLE_NAME           OWNER             DISABLING_VER

------------------------------ ------------------------------ -------------

UTATESTRUCT1          ALMACEN            VERSIONED

UTATTOPOGRA4          ALMACEN            VERSIONED

UTGEOMAGR           ALMACEN            VERSIONED

RELUTNOMDOCAT1         ALMACEN            VERSIONED

... ... ...

¿any idea?

Help will be appreciated.
