After upgrading the Vantage Web Client from 14.0.04 to 14.0.06, the following error messages at logon screen may appeared:
Upgrade is made using the existing Web Client database and existing Tomcat installation which was already at 8.5.31 level.
Release : 14.0
Component : CA Vantage Storage Resource Manager
The upgrading installation from 14.0.4 requires that you create a new Install and Runtime ZFS environment and not reuse any existing one.
Once done, the next logon using APP userid will upgrade the old VantageDB and starts correctly.
