Importing Requestors from CSV

Importing Requestors from CSV

I already have requestors created in SD Plus and I would like to import additional users from a CSV file. In Step 3 of the Import Wizard, it states that "Existing data will be overwritten and new data will be added." Does this mean that all of my existing users will be overwritten? Or does it simply mean that if I have an existing user with the same login name, that particular user will be overwritten?

Is there any way to export existing requestor information so that I can easily compare my potential import list with the existing users and make adjustments to compensate for duplicate users?
