Hi
to prepare for future Projects I created a virtual testing Environment of
1 vCenter Server 5.5 based on Windows Server 2012 R2 (including vCenter Server Update Manager)
2 ESXi-Hosts 5.5
1 HP StoreVirtual VSA MultiSite Cluster
Aim: Upgrade vSphere Environment from 5.5 to 6.5.
Method: Vmware provided Migration Assistant
Upgrade Process did succeed so far. vCenter Server 5.5 has been successfully upgraded to vCSA 6.5 and all Settings and ESXi-Hosts are availible on migrated vCenter Server via vSphere Web-Client.
But: only Web-Client Access does work. It fails while connecting to vCSA by vSphere-Client with message:
An internal error occured in the vSphere Client.
Details: Object reference not set to an instance of an object.
I searched the log-file but still don't have a clue what's the cause of this Problem.
Anyone an idea how to solve the Problem?
thanks
This is a known behaviour.
