Migrate a project from Mantis to Redmine?

Question

The official Redmine documentation teaches how to migrate the full Mantis database, including all users, projects and issues. Is there a way to do it on a per-project basis?

Answer 1

I couldn't find anything on the subject in the open-source community.

There is a commercial tool, however. It's called Task Adapter. We have successfully used it to import a certain project from Mantis into Redmine.

Answer 2

Here is a free program for migrating tasks from mantis to redmine. You can filter mantis issues by project and export it into XML. Download zip archive from here. Unzip it in any folder and run mantis_redmine.exe. Next follow user guide http://ramilnotes.blogspot.ru/2016/09/importissuesfrommantistoredmine.html. This program uses XML export from mantis to import issues to redmine. I've approved it on redmine 3.3.0.
