Update Manager 6.5 issue ""interface com.vmware.vim.binding.integrity.VcIntegrity is not visible from class loader""

Image
This post is related to the issue what we faced today when we replaced the SSL certificates in our setup. 
When I launched the web-client and access the update manager tab,  I get the message  "interface com.vmware.vim.binding.integrity.VcIntegrity is not visible from class loader"





I started off by restarting the VMWare vSphere Update Manager Service for the affected vCSA:
1. Log into vCenter using the administrator@vsphere.local account. 2. Home - System Configuration - Services - Restart



This did not resolve my issue... And we tried restarting all the services by SSH/Console into the affected server and run the following commands:
service-control --stop --all service-control --start --all Still no luck. 
Make sure the certs are applied and it gets reflected in the config file. ( verify if the thumbprint matches)

root@homelab71 [ /usr/lib/vmware-updatemgr/bin ]# ./updatemgr-util config -g | less

An Overview of Hyper-V Live Migration

Hyper-V Live Migration Configuration Requirements


Before a running virtual machine can be migrated from one host to another there are some mandatory requirements that must first be met:
Hyper-V 2008 R2 must be deployed on both hosts. The first version of Hyper-V does not support live migration.
Source and destination Hyper-V hosts must be configured as a Failover cluster with shared storage enabled.
Source and destination systems must be using shared storage (i.e. via SAN or iSCSI configurations)
Source and destination systems must be running processors from the same manufacturer. It is not, for example, possible to migrate a virtual machine from an Intel based host to one containing an AMD CPU.
The virtual machine on which the migration is to be performed must be configured as Highly Available and to use Cluster Shared Volumes.
The virtual machine's Automatic Start Action setting must be set to do Nothing.
All Hyper-V hosts in the Failover cluster must be configured to boo…
