The add-in will not monkey with your due dates. I use them also for some tasks. If you have tasks assigned to outlook categories such as "project", "@office", etc. I believe either the add-in will update the actions for you or you'll need to swing through your list manually. You may need to also assign tasks to projects using the add-in created user-defined outlook field "project"; (When I upgraded I already had a user-defined outlook field called "project", and the values carried over just fine to the add-in. If you've got non-traditional context names you'll just need to define them as contexts in the add-in and then they should work fine.

At least that is my recollection. I would recommend backing up your .ost file prior to installing and doing so off-line if at all possible.
