I have a system that runs RT 3.8.7 with MySQL 4.1.22 and another system that runs RT 4.4.0 with MariaDB 5.5.56. I moved the database from the old system to the new one and granted the necessary permissions to the same user I had in the old database, however, I get the following error:
# make upgrade-database ... Processing 3.9.3 Now populating database schema.  [Tue Nov 7 14:23:06 2017] [critical]: DBD::mysql::st execute failed: Can't DROP 'DelegatedBy'; check that column/key exists at /usr/local/rt/ core/rt-4.4.0/sbin/../lib/RT/Handle.pm line 552. (/usr/local/rt/core/rt-4.4.0/ sbin/../lib/RT.pm:390) DBD::mysql::st execute failed: Can't DROP 'DelegatedBy'; check that column/key exists at /usr/local/rt/core/rt-4.4.0/sbin/../lib/RT/Handle.pm line 552. make: *** [upgrade-database] Error 255
Where would I even start my investigation of this error?
