We are planning an upgrade of our ArcGIS for Server site from v10.4 to v10.7.1. We experienced a service publishing error that could not be resolved with rigorous troubleshooting with Esri tech support, so the advice was to upgrade Server (which we need to do anyway!). We do not have the resources to move to ArcGIS for Enterprise at present. I am reviewing the Esri documentation, but still have questions. Is the Data Store upgraded during the Server upgrade or is this a separate upgrade. Either way, does the upgrade save the data store account password, data store connections, etc.? I have inherited the project from a person no longer here, and I cannot seem to locate a password specified for the data store. I know the webadaptor is a separate uninstall/install new. Are there any other issues to watch out for when doing such an upgrade? Many thanks in advance.
