We'd like to move to redmine, but an import of existing projects with all their facetts is absolutely necessary. Otherwise we must stay with trac :(

Thanks a lot for your great work!

Before processing your Trac database, you need to load the default Redmine configuration as mentioned in RedmineMigrate:

rake redmine:load_default_data RAILS_ENV="production"

Maybe this information may be useful too:

[root@redmine redmine]# gem list rails

#7 Updated by Etienne Massip about 2 years ago

Not sure it will resolve your issue, but Redmine requires Rails 2.3.5 since 0.9, you have to consider upgrade.

#8 Updated by Pavel Pivovarov about 2 years ago

I am update rails for version 2.3.5 but it's still doesn't work. Crashes with the same error.

#9 Updated by Etienne Massip about 2 years ago

It seems to not find your "Feature" tracker, do you have enabled at least the "Defect" and "Feature" trackers in your project "project" ?

#10 Updated by Pavel Pivovarov about 2 years ago

Brilliant!!! Thank you very much! It's work now very well!
