VMware KB: Upgrading to vCenter Server 5.0 best practices
VMware supports in-place upgrades on 64-bit systems from vCenter Server 4.x to vCenter Server 5.0. You can upgrade VirtualCenter 2.5 Update 6 or later and vCenter Server 4.0.x to vCenter Server 5.0 by installing vCenter Server 5.0 on a new machine and migrating the existing database.
This upgrade method makes it possible to upgrade from a 32-bit system to a 64-bit system. Alternatively, if the VirtualCenter or vCenter Server database is on a remote machine, you can upgrade the database. vCenter Server 5.0 can manage ESX 3.5.x/ESXi 3.5.x hosts in the same cluster with ESX 4.x/ESXi 4.x hosts.
You cannot upgrade a vCenter Server 4.x instance that is running on Windows XP Professional x64 Edition to vCenter Server 5.0, because vCenter Server 5.0 does not support Windows XP Professional x64. This article provides information about upgrading to vCenter Server 5.0.

New Book - Administering vSphere 5: Planning, Implementing and Troubleshooting

Written by trainers, this book presents the material utilizing a practical teaching style. This experience will benefit both the new and veteran administrator alike. While this book does cover the new features found in vSphere 5, it doesn't assume that the reader has extensive experience with the previous versions of vSphere. ADMINISTERING VSPHERE 5: PLANNING, IMPLEMENTING AND TROUBLESHOOTING provides newcomers with a solid foundation in vSphere, while also filling in the gaps for more experienced readers.
