Upgrade was completed without any errors and etc.
Do you have Any AD configured? If yes, login with AD user and see if its present.
Or login using the Local Administrator account and see if its present?
Logged in with AD user no Configuration option - exactly same as vsphere.local
Can not login with local administrator account with error: Provided credentials are not valid
Is it an appliance? If yes, Can you login and try with root user?
