As you upgrade from zSpace Classic to zSpace 2019 on your zSpace AIO or zSpace 300, you can keep previously created activities located in the EDU Server/Teacher Dashboard utilizing the Activity Exporter tool. This guide can also be downloaded from here.
Update. Feb 5, 2020, an update has been posted for EDU Server Activity Exporter Tool, version 184.108.40.206374. One additional step to note. The final folder name and location, ExportedActivities, cannot be changed.
Additionally, we have videos which will walk you through this process on the zSpace Technical Resources site.
