If you were using a version of this module prior to v1.0.0, this note applies to you.
Version 1.0.0 of the PSWorkItem module introduced a structural change to the database tables. If you are using a database created in an earlier version, you need to run Update-PSWorkItemDatabase before adding, changing, or completing work items. You should back up your database file before running this command.
Alternatively, you could export your work items, delete the database file, initialize a new one, and re-import your work items.
During the upgrade, a new table column called ID is added to the Tasks and Archive database tables. In the Tasks table, the ID column for existing entries will be set to the row id, which should be the task number you are used to seeing. In the archive table, existing entries will get an ID value of 0 since knowing the original ID number is impossible. This database change corrects this problem. Going forward, the PSWorkItem ID will remain the same when you complete it and move the item to the Archive table.
