upgrade SLES11SP2 --> SLES11SP3 fails

Hi forum,

I am trying to upgrade via SMT.

My repos are:

# | Alias                                            | Name               | Enabled | Refresh
--+--------------------------------------------------+--------------------+---------+--------
1 | SLES11-SP3-Pool                                  | SLES11-SP3-Pool    | Yes     | No     
2 | SLES11-SP3-Updates                               | SLES11-SP3-Updates | Yes     | No

(there is no repo called SLES11-SP3-Core)

but zypper dup says:
