Redmine

Hi there,
Unfortunately, I can't help you directly, but my approach to problems like this is to try not to upgrade in such big steps. I would try upgrading to version 1.2 first... https://www.redmine.org/projects/redmine/wiki/RedmineUpgrade/46

Could you check if changing app/models/member_role.rb as follows fixes the problem?

Hello Go MAEDA,

first thank you very much for your support!

Changing the app/models/member_role.rb as described above fixes the problem.
I was able to migrate the db without any further errors.

Now I see you provide a 36766.patch for this issue.
What is the best way for further migrations? Apply the 36766.patch or edit the app/models/member_role.rb file or both?

Thanks in advance.

Applying the 36766.patch is better. That is the fundamental measure. Changes for app/models/member_role.rb is just a quick workaround.
