We have upgraded from Enterprise 10.7.1 to 10.8.1 on a single machine deployment. We managed to install everything and can configure the new Web Adaptors for Portal and Server. All is ok for now.
When I access the Server Manager is asks me to upgrade it. I make the upgrade and all is ok for a while, then the ArcGIS DataStore becomes unavailble and Server is asking me to upgrade again when accessing the Admin or Manager.
Any ideas why it keeps asking me this? I have re-run the ArcGIS Server Account configuration.
This is a good opportunity to engage support to take a deeper look, but would you be able to attach screenshots of the pages you are seeing prompting the re-upgrade?
