How to migrate data from Mantis to Redmine in 2022?
Added by Crocodile Rat about 1 year ago
I am trying to migrate data from Mantis to Redmine by following this instruction[[https://www.redmine.org/projects/redmine/wiki/RedmineMigrate#Mantis]] and it is "Obsolete: Does not work". Does there any solution work in 2022?

I did a migration from Mantis to Redmine a couple of years ago.
As I can remember, what I did was pulling an old Redmine version (was something around 2.5 or 2.6), did the migration there and updated the Redmine to the latest version.
The result of the migration was not very pleasing as there where deleted issues which messed up the issue numbers. Therefore many of the old issues have got a new issue number in Redmine which was the deal breaker back then.
