  1. Hi, i’ve read your experience from FriendFeed!
    I’ve to upgrade one ESX 3.5 host to vSphere, but is a standalone host.
    I can’t move any VMs away from the local datastore, but i think is sufficent power off any VMs and put host in maintenance mode, before start process, right?
    Regards

  2. Hi Marco, yeah sorry need to write it in the article. I shut down the VM’s are and put the host in mainetance mode. Then I started the upgrade process.

    Good luck with updating! It takes ~20 minutes to upgrade your host.
