I switched over versions from 8.6 to 9.1 for my CUPS server and did not follow this very important Notes. Now the services in the pub are not started, getting database connection error, cannot switch back to 8.6. How can i bring back the cluster?
• Cisco Unified Presence Sync Agent Service
Before you perform an upgrade, this service may be disabled on the cluster (which only runs on
the Publisher node). This action will ensure that user-initiated changes from the corresponding
Unified Communications Manager system during the upgrade do not compromise the upgrade
process. The changes are reconciled when the IM and Presence Service Sync Agent is restarted
in either the current or newer version.
• Publisher node
Switch versions and restart the publisher node before you begin a switch version and restart on
the subscriber nodes. If the IM and Presence Service Administration GUI is operational on the
publisher node, it is safe to initiate a switch version and restart on the subscriber node
