Hello, upgrading from a manually installed 3.10 Koha to a latest stable Koha Debian packages on a new server, I'm facing the following errors, when I run the upgrading database script via: $ sudo koha-upgrade-schema Is it necessary to upgrade in two steps instead, first from 3.10 to 3.12, followed by 3.12 to 3.14? Or do I anyway need to correct all errors manually, by creating missing tables (like the table „koha_INSTANCENAME.borrower_debarments“) which the script updatedatabase.pl fails to create ? Any hints and tips are highly appreciated! Thanks, Jürgen, Stuttgart $ sudo koha-upgrade-schema DBD::mysql::db do failed: Can't create table 'koha_koha3.borrower_attribute_types_branches' (errno: 150) at /usr/share/koha/intranet/cgi-bin/installer/data/mysql/updatedatabase.pl line 6118.
