Successfully upgraded Portal for ArcGIS and ArcGIS Server from 10.6.1 to 10.7.1. Now while upgrading ArcGIS Datastore, it is showing the error as attached. Kindly advice.
I got the same error when I tried to upgrade form 10.4.1 to 10.7.1 in Prod environment. However it worked fine when I did the upgrade in Dev Environment.
