At this time, we do not support direct data migration from Storage Sync to Smart Cache (FKA Turbo). You will need to install the Smart Cache (FKA Turbo) device and synchronize data from the cloud to be able to use Smart Cache (FKA Turbo). 

If you're using Storage Sync to migrate data to Egnyte, switch to Smart Cache (FKA Turbo) once the initial data migration has finished processing.
