Right now I have all my hosted feature layers stored in ArcGIS Online but would like to have them hosted in ArcGIS Server for quicker access in Collector.
Is there anyway to copy the HFS directly from my ArcGIS Online account to ArcGIS Server?
You will need to export/download the data and republish it in ArcGIS Server. If you have ArcGIS Enterprise 10.5.1 or above installed, you could look into using distributed collaboration.
