Yes, you can perform an upgrade from ESX 4 to ESXi 5.5.

as for upgrading the host

1. Insert the ESXi 5.5 installer CDROM in Server CD-ROM drive
2. Boot Server from CDROM
3. Follow the Wizard
4. It's done in 15 minutes.
5. When asked to Preserve VMFS (your VMs on your datastore select YES)

As for vCenter Server, this needs to be upgraded first, same applies, insert CDROM, Perform a Simple Installation, and it will be upgraded.

As for a Good Document, there are the VMware Documents here:-

VMware KB: Installing or upgrading to ESXi 5.5 best practices

Personally, VMware documents are not good, because they have lots of words!

Check your Hosts do support ESXi 5.5 on the HCL.

Personally I would NOT upgrade, and I would install new. (it's quicker, easier, and works!)

Andrew,
I have 3 host with ESX 4 and one brand new server.
So I was going to install ESXi 5.5 on the new server, then create a new Vctr on it, then migrate the vms from one of the 3 ESX 4 host to the new ESXi 5.5 host and then just do a fresh install of ESXi 5.5 on the old host, and then do the same for the other 2 ESX 4 host.
Then I would upgrade the VMware tools on the vms brought over and the update their hardware...
Does this sound good?
