Hi @PaulF
You can do it manually from the Grafana GUI (click the share icon and then export, then take that file and import) or you can do it in bulk using netapp-manager from Harvest.
This snippet from the Harvest admin guide about exporting:

If you use the -export with the old server and API keyconfigured in the netapp-harvest.conf file, and then -import with the new server and API key configured, you will basically move all dashboards. If you want to move a subset of dashboards (ex: you have a Harvest 1.2 on the old server and 1.3 on the new one) after you do the export delete the ones you don't want to move, then do the import. You could also rename the grafana subdir temporarily to help move only a subset.
Hope this helps!
Cheers,
