Historical data was migrated so that graduated person should be in your cloud database. In the Windows App (awdbremote.exe), use the Search at the very top - not the one right above the Clubbers grid. (See the screenshot.) Type in either the first OR last name. If there is only one match, the member form will open. If there is more than one match, there will be a dialog with all of the matches and then you can select the one you want. If you just need data from the record, you can print from the individual tabs. If this 'graduated' clubber is now going to be a leader, you need to create a role record. Once there is an active role record, the person's status will be updated.
If you still can't find the person, send an email to support with the specific name and we'll have a look.
