We fixed the problem in this way: select all the files with this problem (null production number, configuration DC06 and gotReplica='yes'). On the basis of the file name, we have reconstructed the job name and the production number. The information has been stored, production by production, on ascii files (one for each productions). After that, an ad hoc migration script has been developed to copy these files from the old schema to the new schema. Migration done on Tuesday 3 June 08.
