I am in a situation of upgrading esx4.1 to 5.1. I checked the current network configuration and noticed that esx4.1 uses service console and iscsi vmkernel port with nic teaming load balance policy “ route based on ip hash”. I started my vmware from ver 5 and I was told that you have to bind iscsi port and use multi-path, this is the best practice and do not use link aggregation for iscsi, correct me if I am wrong. Here it uses link aggregation, I think I will not be able to bind the nic to iscsi, if I do then it might give break?
I am wondering if I use inplace upgrade option then the current configurations will be upgraded to ver 5.1 and the esxi will work as before in ver 4.1.
