Hi Loretta,
You will first want to download the data from all surveys that will not be the final to a file geodatabase using the steps listed here...View your results—Survey123 for ArcGIS | ArcGIS
You can then use the steps listed below to preserve the editor tracking information contained within the downloaded datasets when using the Append geoprocessing tool in ArcGIS Pro.
1. Login to ArcGIS Online or your portal in ArcGIS Enterprise and select 'Content' from the top panel of choices
2. Select the survey folder which contains the feature layer and form of the survey which you will be appending data to
3. Select the feature layer within the folder > Settings > disable 'Keep track of who created and last updated features' > Save
4. Open ArcGIS Pro
5. Add the previously downloaded file geodatabase data and any table containing attachments to the Current Map
6. Run the Disable Editor Tracking geoprocessing tool against your File Geodatabase data.
7. From the Contents pane—Right-click the feature class from your downloaded dataset > Design > Fields.
8. Check 'Read-Only' for all editor tracking fields (CreationDate, Creator, EditDate, Editor) > Save
9. Run the Append geoprocessing tool with your file geodatabase dataset as the input and the feature layer as the target
10. Login to ArcGIS Online and navigate to feature layer to ensure that all editor tracking information from file geodatabase has been preserved
11. Re-enable the option to 'Keep track of who created and last updated features' from the Settings of the feature layer > Save
The editor tracking information from the appended data should now reflect it's original information and any new records will record the appropriate editor tracking information at time of collection.
Please let me know if this works for you!
