Good morning, Sorry for the re-post. I did not receive any responses so I will try once more in case there are any bright ideas A few days ago it was suggested to me that my environmental variables Koha_conf and PERL5LIB were not set up, which may lead to the problems I had running the migration tools (bulkmarcimport, authority import) . It seems to me that my environmental variables are set up correctly. Here we have run the echo command and also tried bulk authority import again. If this printout below suggests anything new, I am grateful to hear your thoughts. Thanks again! koha@Koha3:~/kohaclone/misc/migration_tools$ echo $KOHA_CONF && echo $PERL5LIB /home/koha/koha-dev/etc/koha-conf.xml /etc/perl/C4 koha@Koha3:~/kohaclone/misc/migration_tools$ ./bulkauthimport.pl -file bulkauthimport.xml Use of uninitialized value $conf_fname in concatenation (.) or string at /etc/perl/C4/Context.pm line 321. read_config_file() returned undef at /etc/perl/C4/Context.pm line 321.
