Currently my company has 4 esx hosts running in 2 seperate HA Clusters. The clusters are currently hooked to Vsphere 4.0 running a 32 bit OS. I have build another box and installed Vsphere 4.1. I need to upgrade my hosts to 4.1 and move them to the new Vshpere 4.1 box. Is their a way to accomplish all of this without shutting down any of my Vmware guests. What would be the correct order to do this migration ? Also Im a running Vmware Enterprise Plus.

The cleanest way to do the upgrade is by a reinstall of ESX. If all your hosts have shared storage amongst them, you can VMotion VMs from hostA to hostB in the cluster. Upgrade/reinstall ESX on hostA, reconfigure it (DNS, NTP, Ntwk, etc), then VMotion your VMs back. Once the VMs are VMotioned back, upgrade VMware Tools. You can then peform the upgrade on hostB. Then, do the same for the other cluster. If your vCenter Server isn't already on a 64-bit OS, that will then need to be upgraded to a new OS before you can upgrade vCenter. I highly recommend going through the upgrade guide:
http://www.vmware.com/pdf/vsphere4/r41/vsp_41_upgrade_guide.pdf, then discerning the best alternative for your setup/organization.

Hope that helps.

Also, take note of the Compatibility Matrix:
http://www.vmware.com/pdf/vsphere4/r40/vsp_compatibility_matrix.pdf; pretty much you can't have legacy versions running - you have to have 4.1 vCenter and ESX/ESXi Hosts together, which is a bit different from prev versions and upgrades.

Can I do the upgrade in the following way.

1) Remove the Cluster from Vshpere4.0
2) Add Cluster to Vsphere 4.1
4) Remove HA
3) Vmotion VM Guests to host 2
4) Do upgrade 4.1 on host 1
5) Vmotion VM guests to host 1
6) Do upgrade 4.1 on host 2
7) Reconfigure HA

Yep, then a #8 would be to upgrade VMware Tools on your VMs.
