We've built a fairly standard map in ArcGIS Pro for a local city (with all their utilities, zoning boundaries, parcels, etc.). Let's assume there are 100+ layers in total. About half of those layers come from outside local utilities (electricity, gas, cable, telephone, etc.) and we get monthly updates of those.
While it's simple to update those in Pro each month, the challenge comes with how to update them in AGOL after we've published.
What is the best way to do this? Publishing as a Web Map from Pro doesn't work as you can't overwrite and it will remove any customizations we've made in AGOL. Publishing the utilities (50+ layers) as Web Layer doesn't work as it doesn't support group layers.
Any recommendations?
