Database upgrade via python fails requiring Administrator but am using an Admin Connection

[JonathanPollack]

I am trying to upgrade a bunch of databases via Python.  I am using the following command...

arcpy.UpgradeGDB_management(d_conn, "PREREQUISITE_CHECK", "UPGRADE")

I get an error saying the connection must be administrator.  "d_conn" is an admin connection.

The same command works when I run it in ArcPro.  What am I doing wrong?

Difficult to pinpoint the root cause of your issue without details. Is this sql server or oracle? It could be insufficient permission of your admin account ? Are there any users connected? Have you tried upgrading the EGDB via ArcGIS Pro using GP tools using this same account? 

Have you reviewed documentaction here -https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/upgrade-geodatabase.htm

Thanks, am using SQL Server.  The exact same account (database connection) works in Pro using GP tools.  I actually copied the python command from Pro and pasted it into my Python script.  No users are connected.
