Hello,
I am trying to perform an upgrade of ArcGIS Datastore from 10.6.1 to 10.8.1 following the following instructions
Upgrade ArcGIS Data Store—Portal for ArcGIS | Documentation for ArcGIS Enterprise
The Datastore application upgrades successfully in Programs and Features, and the Datastore service shows as running. However, both the configuredatastore.bat and https://localhost:2443/arcgis/datastore processes fail with the following error

Additionally, running describedatastore.bat produces the following error
Error encountered: The data store machine may not have been initialized
Has anyone successfully upgraded datastore successfully using the link above? Or has anyone seen these issues?
Thank You,
W
