* remove assignments (issues are set to 'no category')
* reassign issues to another category (if at least an other category exists)
If no issue is assigned to the category, it's deleted silently.

A project module (eg. issue tracking, news, wiki,...) is a set of permissions that can enabled/disabled at project level.
For each project, modules can be enabled on the project settings view ('Modules' tab).
This requires a specific permission: 'Select project modules' (if this permission is turned off, only Redmine administrators can choose which modules a project uses).
When applying this migration, all modules are enabled for all existing projects.
