I have just installed a fresh v4.1.1 on a new system and tried restoring a mysql database backed up from a v.4.0.5 installation. Unfortunately the restored database gets (almost, but not entirely) inaccessible after the restore. I can login, but only can see very limited sections of it.

I also tried restoring exactly the same db on a new clean v4.0.5 installation with no issues. I spent 2 days on this, and sadly I cannot find a solution.

Here's the steps to reproduce:

1. Installed a fresh v4.1.1 + restored (successfully) a mysql database created in v4.0.5:

gunzip -c /home/xxx/backup/mysql_2020-05-17.gz | sudo mysql --defaults-file=/usr/as/mysql/.my.cnf redmine_default

2. I can successfully login to redmine with the usual After the login I do see the projects list and the issues list.

3. However, if I click on any project or issue, I get an Error 500 page

4. Inspecting `/usr/share/redmine-4.1.1/log` after clicking on a project shows:

I think you have not run bin/rails db:migrate.

Indeed. Ref.: Restoring a db in v4.1.1 gives Error 500, while in v4.0.5....

@A Fora: please keep this in the forum-thread.
