I've been slow to migrate all of my vSphere environments to vSphere 5. This has been partly due to new features not applying to the smaller environments but also just that I've been lazy. Well, now is the time to go ahead and get all of my environments up to vSphere 5.
vSphere 5 Update 1 was released on March 15 (See Release Notes at VMware.com). This is a big deal, as there are number of fixes for the vSphere 5 features, which may be important for larger environments that take the "Wait for the first major service pack" approach for new platforms.
There are not many new features with Update 1, but they are noteworthy.
- Update 1 adds support for newer processor families by both AMD and Intel that have become available since August when vSphere 5 became generally available.
- Additional guest operating system support includes Mac OS X Server Lion 10.7.2 and 10.7.3.
- New drivers are available for a few storage products. With all of the updates and driver configuration options, it is always a good idea to reference the VMware Compatibility Guide as you plan an upgrade. There also may be products that are not necessarily on the compatibility guide as you go upward in versions.

The recommended way to upgrade hosts is via vSphere Update Manager (included as a separate install on the vCenter download). This will take hosts with their configuration (and inventoried VMs/templates) up to the new release, generally without issue. Reinstallation is also an option for simple configurations. It is imperative that vCenter is updated first, however. You can't have a newer host talking to an older vCenter; unless you like to fix problems.
