I am looking for the best way to migrate survey data from 3 earlier survey versions into the current Survey123 hosted feature layer. The surveys were similar and I have renamed and added fields as appropriate to make them all the same. I then used the "Append" tool in ArcGIS Pro to combine into the current survey hosted feature layer. That all worked swell EXCEPT that the Creator and CreationDates have all been overwritten to my login and todays date. I then tried to use "Calculate" to copy the original data into the appropriate fields. However editing is not possible. I did try the "Disable Editor Tracking" tool but it can't "see" the hosted feature layer in question as it wants feature class, table, or mosaic dataset as the input dataset. I also unchecked the "Read Only" buttons in the "Fields" View. But that didn't work either. And if I use the drop down to select "Data Source" there is nothing configurable. Sooooo, how can I fix this?
