Hello developer,

I would like know step by step migration form redmine 4.1.1 to Open project in Debian 9.

Here I attached my Redmine environment.

  Rails version                  5.2.4.2
  Environment                    production
  Database adapter               PostgreSQL
  Mailer queue                   ActiveJob::QueueAdapters::AsyncAdapter
  Mailer delivery                smtp
SCM:
  Subversion                     1.9.5
  Git                            2.11.0
  Filesystem                     
Redmine plugins:
  no plugin installed

Thank you

Hi John,

There is a separate GitHub repository that documents the migration steps and also contains scripts that may be helpful: https://github.com/opf/redmine-to-openproject.

Please note that you would need to downgrade from Redmine to Chiliproject and then upgrade to OpenProject. The GitHub repository includes steps to upgrade to OpenProject 7.4.2. Picking up from there, you can then follow our update guide: https://docs.openproject.org/installation-and-operations/operation/upgrading.
