I have been tasked to update our ArcGIS Server and Portal for ArcGIS accounts that run on our Windows 2012 servers. We use the same Windows account to run ArcGIS Server, GeoEvent Server, ArcGIS Data Store, and Portal for ArcGIS. I have read through the ESRI instructions for using the ArcGIS Server Account utility for ArcGIS Server and the configureserviceaccount utility for Portal for ArcGIS, but I'm not sure how/if those utilities affect the account used to run GeoEvent Server and ArcGIS Data Store. Is there a separate utility for updating those accounts or does the ArcGIS Server Account utility also update those? If the answer is no to both of those questions, how do you go about updating the account (other than changing it with the operating system settings)? I've never had to update these accounts before so this is all new to me. Any assistance on this situation would be greatly appreciated. Just for reference we are running ArcGIS Enterprise 10.6.1.
For Data Store account the configureserviceaccount command utility is available

Thank you for the information. Any idea about how to handle GeoEvent Server?
