I have a small VMware lab setup at home that I use to test things out before work deployment. As part of this, I used the free VMware vSphere4 license. This does not include vCenter support.
Reading through the docs, it appears that the only listed upgrade path that I can find is by using the Update Manager.
Not having gone through a VMware upgrade before, I'm looking for options that will let me upgrade from 4.1 to 5 without having to resort to rebuilding the entire box.
