Hi, 

I installed OpenProject 11.4.1 with PostgreSQL 12.8 on Ubuntu 20.04 (focal) and "Demo project" works fine. 
After that I wanted to migrate my old openproject database dump (mysql - don't know which version it was - I guess V7.1) to OpenProject 11, running your shell script /opt/openproject/script/migration/migrate-from-pre-8.sh 

I called it in the following way: 

/opt/openproject/script/migration# bash migrate-from-pre-8.sh 85.214.243.8 /private-backup/mysql-backup/openproject.sql sql 

A couple of errors / warning have been displayed, but finally it stops after 

2.5) Migrating from 10 to current (11) 
. 
. 
. 
migration unsuccessful. Please check migration.log 

Attached you can find my migration.log. On the same folder the file openproject-mysql-dump-8.sql was created by your bash script. 
In migration.log I see several errors regarding unknown column "updated_on", but I'm not able to fix it 

StandardError: An error has occurred, this and all later migrations canceled: 
PG::UndefinedColumn: ERROR:  column "updated_on" of relation "users" does not exist 
LINE 1: UPDATE "users" SET "admin" = $1, "updated_on" = $2 WHERE "us...

Please could you help me? 

Thanks in advance!
