Unified Manager is not accessible after upgrade. Upgrade may appear to stall at 77%
--------------------------------------------------------------------------------
Problem Description
When upgrading to either 3.6 or 3.7, it appears as if the upgrade stalls at 77%. The upgrade has not actually stalled. The BCM web server has become unavailable causing the upgrade wizard to no longer receive updates and, therefore, appearing as if the upgrade has stalled.
All services on the BCM will be operational other than the web server (Apache service). When trying to access Unified Manager, your web browser will return "page can not be displayed".
The upgrade would have completed successfully.
Problem Resolution
Nortel are aware of the problem and are working towards a resolution.
The upgrade would have finished successfully. However, a repair to Apache certification files is required in order to start Apache Service, thus Unified Manager will then be available.
