In order to keep monitoring your virtual infrastructure after upgrading SCVMM to 2012 R2, you will need to update SCVMM Admin console installed on the Veeam ONE server. Did you do this?

Yes, of course.
Can you please tell me what account do you use to connect to these hosts? The same as specified for SCVMM server connection?
