Hi all, We have upgraded from version 1.2.2 to version 2.2.9. We are having issues trying to get a good marc database of our biblio records. When in version 2.2.9 we run koha2marc.pl -d we get "Column 'bibid' cannot be null" for all records. We then have to go back to an older version, and build it from there. After doing this we don't get great results. For example we only had 2 "245" title records so searching by title doesn't work unless you use one of those titles. Any guidance on how to build a marc database with our biblio information would be greatly appreciated.
