Manual Host Restore Using CLI

Going to be upgrading some hosts (manually) in the next few weeks. I have the host configs backed up. Once I've upgraded the host and reassigned the IP, I can then initiate the restore via CLI then just add the VM's back into inventory. Thats it right? Has anyone ever run into issues with the restore using CLI?

1) If you are not using enterprise hardware, in 5.5, drivers for some hardware that used to be included are no longer included. In my case, Realtek network driver IIRC. You just need to make sure you are actually doing an update and not a reinstall. The previous existing drivers should still work.
2) It may just be my own lack of attention in going through the logs and esxcli output. But after the upgrade, I couldn't really tell if the upgrade was successful or not. I didn't actually notice until I rebooted the host.
The second item wasted a bit of my time because I couldn't quite figure why it was failing but in actuality, it was successful.
Upgrading vCenter from 5.1 to 5.5. Upgrading three 4.0 hosts to 5.5 and one 5.1 to 5.5 (Primary 4 host cluster). vCenter is a VM residing on one of the 4.0 hosts. Will be physically moving hosts to a datacenter along with a dialer that supports a multi-site call center. Will be switching SAN switch ports to 9000 mtu for jumbo frames, enabling EVC, HA and DRS. None of this is enabled right now and that is just unacceptable in my opinion (I didn't do initial setup). Will be purchasing another host for HA purposes because this 4 host cluster is nearly maxed with everything on. Will be crystal marking the storage, testing vmotion, testing HA failover for the priority VM's, along with other things associated with the dialer. All of this done over night and ready to go at 7am the next morning. I will be testing most of this in my home lab but you can see why I don't want any surprises.

When you say you backed up the host configs, do you mean with get-vmhostfirmware? If so, I don't know if you will be able to push that config back. I backed up a host so I could take that image and push it to other hosts, and unless I patched the hosts that were receiving the image to the same level that the original host had, it would not work. But that was with PowerCLI 5.0, maybe PowerCLI 5.5 will allow it.
Sorry, you did write CLI, but for some reason when I see VMware and CLI, my mind automatically goes to PowerCLI. My mistake, I hope the upgrade works out.

Hasn't been done yet. Was at the datacenter all day today prepping. Actually put in server and storage switches today. Threw esx on a pc and put it in the rack for some testing. Have to convert a entire building from analog to voip first. Going to be posting my HA plans here soon to hopefully get some feedback.
