Error running backup of the same test Windows 10 empty VM
20.07.2022 22:35:34 :: Processing Win10at67 Error: Ссылка на объект не указывает на экземпляр объекта.
(object reference not set to an instance of an object)

My steps - one-by-one - I need to turn from vCenter 6.0 to 6.5 or 6.7 because of Adobe Player end-of-work

1. open vCenter 6.0 and delete the host (there is only one host) from inventory
1.1. shut down the vCenter 6.0
2. install vCenter 6.7 on the same host with FQDN (and reverse DNS too) - another than 6.0
2.1. add the host to the new vCenter 6.7 - update certificates and all
2.2. reboot the vCenter 6.7 - to avoid <Unable to connect to the MKS: internal error> of [VMware vSphere Client 6.0] - now okay
3. add new vCenter 6.7 credentials in VEEAM Backup and Replication 9.5
3.1. Remove unavailable VM from vCenter 6.0 and add the same VM from vCenter 6.7
4. Run the same task and have this error
20.07.2022 22:35:34 :: Processing Win10at67 Error: Ссылка на объект не указывает на экземпляр объекта.
(object reference not set to an instance of an object)

The same 1-2-3 steps for vCenter 6.5 is okay - task make full backup (it cannot understand the VM is the same)

Hi

For vSphere 6.7 U3, at least Veeam Backup and Replication 9.5 Update 4b (build 9.5.4.2866) is required.
Please update your environment to the latest V11a build. Your build is already in the end of support stage.
