added stand alone host to vmware farm ESXi 4.1

We have a vmware farm running ESXi 4.1 and I have a stand alone host running ESXi 4.1...a few of you have helped me move the VMs from the stand alone to the farm, now I hope to vmotion the VMs, that are on our weakest server on the farm, to other hosts and remove that host, then bring in our formerly stand lone ESXi host and make that part of the farm. Then, of course, vmotion some of the VMs to the new, more powerful, host on the farm. Is this a simple procedure? From what I have seen with VMWARE and VMOTION, hopefully this should be pretty straight forward. I know i can easily vmotion VMs from the host we no longer need and there is no longer any crucial data on the stand alone host. What is the best procedure?

Select the Virtual Machine, Select MIgrate, and select the host and datastore you want to migrate (move) the Virtual Machine to.

(make sure you have no snapshots on the VM)

When you want to remove the host from the vCenter Farm, Select the Host Server and Click Remove.

I am not sure I understand you step one or maybe I did not explain my question properly....We have a VCENTER with a DataCenter under it then a Cluster....under the cluster we have 4 hosts. I want to remove the oldest and slowest host and bring in a newer host that has the same version of ESXi 4.1 installed on it. After doing some research I would;

1. vmotion all the VMs off the older host
2. right click the cluster and remove the older host
3. right click the cluster again and select ADD host
4. enter the IP address and root name and password of the newer host we want to bring in
5. click next and hopfully that will bring in our newer host
6. vmotion some VMs over to the new host now that it is on the farm

Is it that simple? I know you know a lot more about this then I do

ooops I just realized our stand lone ESXi host, with the newer server on it is
VMware ESXi
Version 4.1.0
Build 2602247

our Vcenter shows as;

Vmware vCenter Server
Version 4.1.0
Build 258902

Will this be a problem? What can I do to get them on the same build??

I think we only have 4 licenses, does that mean I need to remove the old server before I can add the new server? It is not a big deal, but I always feel more comfortable making sure the new box is working before I removed the old one

you will probably get an error, because you will need to allocate a license to the server on addition. ESXi free does not include a license for vCenter, and cannot be added.

So you are going to have to move off all VMs, Unassign license, remove server, add new server, assign license.
