Thanks for the reference bug and the command.  Unfortunately, when I execute the command suggested I receive:

ERROR 1832 (HY000): Cannot change column 'branchcode': used in a foreign key constraint 'reserves_ibfk_4'


Any other thoughts?

Thanks again!

I had the same issue upgrading from Koha to

This came in handy - https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31086


Log in to MySQL/Maria, change database to the instance DB;


ALTER TABLE reserves MODIFY COLUMN `branchcode` varchar(10) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT 0;


Upgrade Schema.


Your upgrade will complete.

Good evening everyone,

   I'm trying to upgrade a Koha environment from to the latest, including upgrading Debian OS from jessie to stretch.  This
was originally a package install on Debian Jessie. I did the upgrade
successfully in a "test" environment and am now trying on my production
system.   After my first attempt I got the "welcome to Koha, please login
using the default Koha user' screen, so I deleted that DB completely and
restored from the backup I took right before the upgrade.   Now when I try
to execute 'koha-upgrade-schema <koha_site>' I get:

Upgrade to  [21:40:11]: Bug 31086 - Do not allow null values in
branchcodes for reserves

ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Cannot change
column 'branchcode': used in a foreign key constraint 'reserves_ibfk_4' at
/usr/share/koha/lib/C4/Installer.pm line 739

Any ideas?
