Backups of Hyper V Confusion Windows 2012 Serv / Win 2012 Serv R2?

Hi

Want to share very special that 

We want to take the backups of Hyper V on windows 2012 R2 by using NB7.5.0.7 Master and Client Versions

as we have gone through this tech note :http://www.symantec.com/business/support/library/BUSINESS/xCL/TECH76648/nbu_7x_scl.html

but when were takinh the backups it was giving error 

error Validating Hyper v Machine name
Server failed to list VM's (-1)

So we have taken the support from Symantec Team

and they remind us that A new Symantec Technote has been released in NOV 2014 having compaitibilty of VM's 

i.e. http://www.symantec.com/docs/TECH127089 updated NOV 2014 NetBackup 7.x in a Virtual Environment: i.e

showing that Hyper V 2012 Server R2 supports for Virtual starts from NB 7.6.0.2

So We have to upgrade Master And Client to NB 7.6.0.4 Latest version for this
