After upgrading to UIM 8.47 I'm unable to access the UIM Server Home Page: http://<Primary Hub IP>/uimhome
This issue is most likely caused by the "uimhome" webapp not being present on the primary hub wasp. Browsing to the UIM Server Home Page returns the following error:
HTTP Status 404 - /uimhome/
type Status report
description The requested resource is not available.
