    Done mine at the weekend, unless you need vCenter for 1-2 hours it can be done at anytime.... the hosts will carry on running their VMs.

    Hosts can also be upgraded at anytime if you have the spare capasity to move VMs over.

    Depends on your setup. I've got a SAN and 3 ESxi servers. I can just take vmotion the vm's off one and update it. Upgrading vcentre can be done anytime. It doesn't affect the running of the esx servers.

    I have a vCenter server as a VM, we've got 2 ESX hosts and they are connected to a san

    I'll start with the vcenre update and then go onto a Host update - can I update one host and have the HA/vmotion still work or will that only go between the same versions of esx?

    It can never harm to do a snapshot, but a rollback can make things worse. Especially if you run other services on your Virtual Center box.

    Good resource for upgrade info can be found here, also includes upgrade training videos.

    in process of upgrading atm... the VI Client/server upgrade went smoothly and first of the ESX boxes is now upgrading

    EDIT: Bugger... in the ESX upgrade process I have got a:
    TSC: 34771057 cpu0 :0)Init: 461: The Execute Disable/No Execute CPU feature is not enabled for this machine.
    Edit: Edit: For anyone who gets this error then make sure you have the memory execute thingy enabled in BIOS and also make sure you have VT enabled

    thanks for everyones help on this one - one host upgraded and happy, one to go

    ok... not good... any advice welcome...

    I've got my vcenter updated and the ESX host are at version 4... however I haven't got the tools updated on all of them yesterday and one of the hosts dropped off over night and the hosts didn't migrate to the other host. I have the host that went down up but it's still showing as disconnected. and all servers that were on there are showing disconnected and I cant migrate them manually!

    Can you ping a host service console? is it alive?

    Can you disconnect one host from vcenter and re-add i it in?

    If the vSphere host does not have access to a DNS server (with an entry for it in) it will take around 15 minutes for the vsphere management to be started up after boot, although it will work as normal apart from this delay.
