csv-import questions

If I have existing users in Mantis with the same username, will importing tickets via CSV that have the same username result in duplicate usernames?

In principle not but to be sure, try it out in a test environment.

Is there a sample CVS file that we can use to model and build our own import file from?

I don't know what columns can be present and what order to have them in. A sample file with column headers showing every available field that can be imported (not just a small subset of) would be immensely helpful.

Could someone provide a sample and fully populated CSV file that the Import Issues plugin accepts?
