Upgrade ESX 3.5 to 4.1 or fresh install?

I am in the process of upgrading 5 ESX 3.5 hosts to 4.1. I have already created a new 4.1 vCenter server and am ready to do the hosts. I would like to just upgrade from 3.5 to 4.1 using Update Manager. Has anyone done this, would the best thing be to remove them from the existing vCenter, add them to the new one and update each one?

Anyone had any issues upgrading, would anyone do the fresh install? One of my issues with the fresh install route is that the servers are managed so I will have to rely on the hosting company to do the work which also means waiting on them.
