Hello koha folks,

###

I hope this is the correct list for this kind of email

###

We are currently exporting about 500k recods from a dabis system into a new koha installation.

the export file (MARCXML) goes through some transformations using catmandu.

I imported the first 25k records using this command:

```

bulkmarcimport.pl -M MARCXML -file tmp/marc_001.xml

```

after inspecting the records some of the catmandu fixes had to be updated and now im trying to update the existing koha records with the new marc_002.xml file.

```

bulkmarcimport.pl -M MARCXML -update -isbn -file tmp/marc_002.xml

```

this gives me alot of these errors:

```

WARNING: Updating record  failed at /usr/share/koha/bin/migration_tools/bulkmarcimport.pl line 470, <GEN24> line 190.

..Use of uninitialized value $originalid in concatenation (.) or string at /usr/share/koha/bin/migration_tools/bulkmarcimport.pl line 470, <GEN24> line 194.

WARNING: Updating record  failed at /usr/share/koha/bin/migration_tools/bulkmarcimport.pl line 470, <GEN24> line 194.

```

I also tried using -match but I havent figured out how the parameters for -match are supposed to look like

```

bulkmarcimport.pl -m MARCXML -update -match="001" -file tmp/marc_002.xml

```

```

.Use of uninitialized value $recorddata in pattern match (m//) at /usr/share/koha/bin/migration_tools/bulkmarcimport.pl line 603, <GEN24> line 2.

unable to search the database for duplicates : No query entered at /usr/share/koha/bin/migration_tools/bulkmarcimport.pl line 323, <GEN24> line 2.

```

help or pointers are appreciated.

cheers
