Issue/Introduction

After finalizing a ZDU upgrade and verifying that all processes are connected to the new version (e.g., v24.4.4), the banner "System upgrade is in progress" remains visible to users. This occurs even when the upgrade wizard appears to be finished or if users were forcefully disconnected during the process.

Cause

The banner remains because the ZERO_DOWNTIME_UPGRADE entry in the UC_SYSTEM_SETTINGS table was not automatically set back to 'N' during the finalization step of the upgrade wizard.

Resolution

Issue Verification

• Environment Check: Verify the system version using MQLS or by checking the WP logs. If logs show MixedMode='N' and ZDU-Step='0', the engine has functionally completed the upgrade.
• Settings Check: Check the UC_SYSTEM_SETTINGS table in Client 0 for the ZERO_DOWNTIME_UPGRADE key.

Step-by-Step Resolution

1. Log in to Client 0 as an administrator.
2. Navigate to the Administration perspective.
3. Go to Automation Engine Management -> System Upgrade.
4. Review the screen state:
   • If the screen shows grayed-out options at the top with an explanation of the wizard, proceed to Step 5.
   • If it shows a black "1. Initial Data" and a note about compatibility mode, click the Cancel button in the lower-right corner of the screen to exit the active wizard session.
5. Open the UC_SYSTEM_SETTINGS (static variable) in Client 0.
6. Locate the key ZERO_DOWNTIME_UPGRADE.
7. Update Value 1 from Y to N.
8. Save the changes. The banner should be removed immediately from the AWI.

The AWI banner is triggered specifically by the ZERO_DOWNTIME_UPGRADE setting in the system variables. Manually reverting this to 'N' clears the UI flag without impacting the already-upgraded engine processes.
