Hallo,

  If the SRID 31497 from 0.8 is equivalent to SRID 31467 in 1.0
then you could just replace the old SRID in the dump file with 
the new one. 
 
  If it's a new system, you could restore your data to a 
temporary table and use something like 

   INSERT INTO new_table(id,...,geom)  
     SELECT 
        id,
        ...,
        transform(geom,31467)
     FROM temp_table;

   
Gruß,
Gustavo
