Error Message :
U00011898 Switch server mode to DWP not allowed during Zero Downtime Upgrade.
The following two hints were missing in the overview section of the Zero Downtime Upgrade (ZDU) documentation:
- While you are in compatibility mode, you are not allowed to switch a Worker Process (WP) to a Dialog Process (DWP).
- When an Automation Engine process running the old version stops, it cannot be restarted. When all Automation Engine processes running the old version have stopped (e.g. because of a power failure), the ZDU finalizes the upgrade process. No rollback is possible in this case.
OS Version: N/A
Root Cause: N/A
Update to a fix version listed below or a newer version if available. where the above two hints are now included in the overview section of the ZDU documentation.
