ESX migration to Vsphere question

[tonyhard]

Hi

We are just about start doing a esx 3.0.2 to 4 upgrade. We are not doing a inplace upgrade up but a migration to a new vsphere setup.

My question is

once we have vsphere 4 all up and running with vcentre etc etc, can we import the old esx hosts 3.0.2 from virtual centre 2.4 into vsphere and will the VM servers on the hosts be automatically imported into vsphere ? That is when we add the 3.0.2 host (say hosting 20 virtual servers) into the vcentre 4 console will the virtual servers be imported at the same time ? or do we have to import the virtual machines one at a time ?

many thanks

Running and registered VMs will be automatically added to new vCenter.

vCenter Server can handle both hosts, but for the 3.x version it require a license server (or the trial mode).

When you add the old hosts, all existing VM will be automatically imported into the Discovered VM folder.

Then you can use a cold migrate to move the VM from one host to another.

As AndreTheGiant stated, you'll need to have the license server in place for the older hosts as vSphere 4 is a license file based architecture whereas 3.x used the license server model. Just to save you a little time, here's the download for the 3.x license server. I went through a similar process a while back moving to vSphere and everything went very well.
