After synchronizing the RACI configuration through the portal, links to users in the A configuration that determines the managers to assign to tickets are not updated. As a result tickets are assigned to the default admin or to previous manager.
Set the following properties to 'true':
raci.sync.override.accountable.roles
raci.sync.override.accountable.resources
Then perform the RACI synchronization. The accountable configuration (A configuration) will contain the link to the user that is written in the role/resource field marked as the owner in the universe definition.
