But as we are doing esxi host upgrade using cisco customized image which includes nenic--1.0.29.0 driver version which is also supported by Vmware. So now which driver should I need to update ?
Should I keep cisco customized image driver ,i.e nenic--1.0.29.0 ? I
Should I upgrade Cisco recommended driver ? if so ,then how can I update different driver version for each model ?
It’s really confusing for me to update drivers to ensure that host should not have any cause after upgrade host to 6.5 U2
Thanks in advance for your support
