Hello all
just switched from Mantis to Redmine - love it. The rake script in the Redmine source didn't work very well with the current Mantis release (1.2.0) and also wanted to destroy my (already existing) data in Redmine.
So i wrote a non-destructive, kind of flexible migration script. If someone runs into the same problem: you can download and read the usage description here: http://blog.foaa.de/2010/04/non-destructive-migration-from-mantis-to-redmine/. So far it is only tested with the 0.9.3 from debian stable backports..
Cheers
Ulrich
