ESXi Confiuration Cloning

We have 2 Dell R710's for all our virtual machines and we just upgraded so each has 32GB of ram so we house all machines on one and use the other as a backup. One machine had ESXi 4.0.0 and the other had the same version that we successfully upgrade to 4.1. The other machine had lots of trouble due to the SD card being improperly configured to accommodate the update. I went to the Dell site and downloaded the latest copy of 4.1 for our R710 and using the NON embedded version, I installed it to the SD. After it being booted up I tried to restore the config from 4.0.0. It was a no go, even after the VMware tech said it was possible? So I decided to just clone the config from the other R710 that was working perfectly and had the config just the way we wanted it since they are both EXACTLY the same machine. I did the clone process the manual way by backing up the config on the working "model" R710 and just restored it to the blank R710. I had to hurry and change the static IP's I had on the one i just restored the settings too, add it to the cluster and remap the old virtual machines that were sitting in the data store. All worked perfectly. Awesome!
