Redmine

Hi,

our old redmine server:

Debian 8
Environment:
  Redmine version                3.2.1.stable
  Ruby version                   2.1.5-p273 (2014-11-13) [x86_64-linux-gnu]
  Rails version                  4.2.5.2
  Environment                    production
  Database adapter               Mysql2
SCM:
  Git                            2.1.4
  Filesystem                     
  GitRemote                      2.1.4
Redmine plugins:
  redmine_agile                  1.4.5
  redmine_dmsf                   1.5.6
  redmine_git_remote             0.0.1
  redmine_image_clipboard_paste  1.0.0
  redmine_issue_templates        0.1.1
  redmine_my_page                0.1.9
  redmine_zenedit                0.0.2

Our new redmine server:

Ubuntu 20.04
Environment:
  Redmine version                4.2.3.stable
  Ruby version                   2.7.4-p191 (2021-07-07) [x86_64-linux]
  Rails version                  5.2.6
  Environment                    production
  Database adapter               Mysql2
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter
  Mailer delivery                smtp
SCM:
  Git                            2.25.1
  Filesystem                     
  GitRemote                      2.25.1
Redmine plugins:
  redmine_agile                  1.6.2
  redmine_git_remote             0.0.2

We would now like to install the DMSF plugin on the new server as well.
When I follow the installation instructions and enter "RAILS_ENV=production bundle exec rake redmine:plugins:migrate NAME=redmine_dmsf", I get some errors.

Quite often there is the error that a column already exists in the DB. If I comment out the corresponding line, the error doesn't come anymore, but it finds many more lines with the same problem.
If I comment them all out, I have the problem in the later course that he can not rename something etc..

Is there a good solution to fix the problem? If more info is needed, feel free to ask....

Thanks a lot and best regards
Andreas
