A failure will occur when upgrading to Process Automation  04.3.02 if in a previous version of  Process Automation a customer has configured both the  “Network Utilities” and “File Transfer” modules (or connectors), at the domain level. This problem will NOT be manifest if just the “Command Execution” module has been previously configured.  The upgrade will not complete and you will be unable to rollback to the previous release which could leave your orchestrator in a degraded state.

Issue with the domain.xml for C20Service.  This is now listed as a known issue to be fixed in the installer for a later release of Process Automation.
