I have read where you can use update manager to update hosts from 3.x to 4.x then to 5.x. I have also read where 3.x is not supported. I know it is not supported from a direct upgrade from 3.x to 5.x. But is it not true that update manager does support 3.x host upgrades but through a two step process...3x. > 4.x > 5.x?
