I have a GDB set in local coordinate system on ArcGIS Pro map. I then shared map to ArcGIS online [reprojected to Spherical Mercator] and turn on feature editor tracking and sync. Next, I imported original GDB and ArcGIS Online Services URL to data warehouse [FME]. Manipulated coordinate system to match and compared geometry of same feature. It resulted with NW shift of 3 feet. When surveying centimeter-grade, this shift is unacceptable.
Is there a best practice to retain feature's original geometry when sharing to ArcGIS Online then back to GDB???

Hi @AlexanderLynch2 thanks for this post. If I'm understanding this right, you're comparing the location of points from the following two workflows:
We would like to get this to a Support analyst to take a closer look at the data and workflow involved. Let me know and I can get a case going for you. In the meantime, would you be able to attach a zipped file geodatabase with some sample data?
Hi @AlexanderLynch2 - sorry for the delay in getting back to you on this. Thank you for including the sample data - I haven't been able to reproduce this issue. Please see my steps below and let me know what I need to alter to see the issue. Alternatively, I can get a Support case started for you and an analyst can test the workflow and data extensively.
I am also finding the same issue with everything moving 3.3 ft. I also use share from ArcGIS Pro to web map. I share a map that is in Vermont State Planes and FT. When I export it is in WGS 84 and meters. All data collected using survey 123 Elevation is in meters and the old data is in ft.
