[Koha] Migrating data from 2.2.9 to 3.00.X: item problems

[Magdalena Söderqvist]

Hi, 
SIPRI library is attempting to migrate catalogue records from 2.2.9 to 3.00.06.008. I know the latest stable release is 3.00.05, but our IT-guy got a little carried away (and then he went on vacation)! The upgrade however solved a major problem with blank record pages in the opac, but we still have some remaining problems we need help solving. Others have reported similar problems but I haven't been able to figure out how their problems were actually solved, hence this appeal. 

Problem 1: 
When importing a normal biblio with only one item to the new version, the one item is split up in two, with Shelf location on one row and Barcode on another. The rest of the item specific information is hidden. If I edit the record and delete one of the items and move the barcode to the remaining item, all the hidden information shows up. 

So the question is, what is wrong? We use 952c for Shelving location and 952p for Barcode. 
Also, we don't use actual barcodes, but instead use the barcode field for our accession numbers, for example G10/123 or 10/124. 

Problem 2: 
We occasionally catalogue chapters as separate biblios, and when doing so, we have used the same barcode/accession no. for each chapter belonging to the same book. It worked fine in 2.2.9, but since 3.0.x does not seem to accept duplicate barcodes this has now become a problem. Would it be possible/complicated/stupid? to alter the bulcmarcimport.pl to make it allow import of biblios with duplicate barcodes? Is there a better solution? 

Any help you can offer is much appreciated. Sincerely, 
Magdalena Söderqvist, Librarian 
SIPRI Library (Stockholm, Sweden)
