Reconfiguring the ArcGIS Data Store as storage for scene layer tile caches after an upgrade from 10.3.1 fails if a custom database is configured as the managed database.
This was not reproduced using the SQL Server as the managed database originally configured with the ArcGIS Data Store at version 10.3.1 with the nosql option.
During upgrade, a check was performed on permissions to the c:\arcgisdatastore directory and then subsequently upgraded correctly.
