Upgrade vCenter and ESX/ESXi Hosts
After you upgrade vCloud Director and its database, you can upgrade the vCenter servers and ESX/ESXi hosts
attached to your cloud to enable new vCloud Director features.
This upgrade is optional, but several vCloud Director features depend on it. For a list of vCloud Director
features that depend on new versions of vCenter and ESX/ESXi, see “vCloud Director Hardware and Software
Requirements,” on page 9.
Procedure
1 Upgrade the vCenter server.
2 Upgrade each ESX/ESXi host that the upgraded vCenter server supports.
a Use vCenter to put the host into maintenance mode and allow all the virtual machines on that host
to migrate to another host.
b Upgrade the host.
c Take the host out of maintenance mode.
NOTE To ensure that you have enough upgraded host capacity to support the virtual machines in your
cloud, upgrade hosts in small batches. When you do this, host agent upgrades can complete in time to
allow virtual machines to migrate back to the upgraded host.
After the host is upgraded, vCloud Director detects the new version and upgrades the host agent.
Upgrade vShield Manager
After you upgrade vCloud Director and its database, you can upgrade the vShield Manager servers attached
to your cloud to enable new vCloud Director features.
IMPORTANT A new installation of vShield Manager cannot work with an existing version of vCloud Director.
After you upgrade a vCenter server attached to vCloud Director, you can upgrade the vShield Manager server
associated with the upgraded vCenter server. Although this upgrade is optional, several vCloud Director
features depend on it. For a list of vCloud Director features that depend on the new release of vShield Manager,
see “vCloud Director Hardware and Software Requirements,” on page 9.
Upgrading vShield Manager interrupts access to vShield Manager administrative functions, but does not
interrupt network services. Upgrading a vShield Edge appliance briefly interrupts service on the networks
that the appliance protects.
Prerequisites
At least one upgraded cell in your vCloud Director installation must be running before you begin this upgrade.
The cell is responsible for writing data about the upgraded vShield Manager to the vCloud Director database.
Procedure
1 Upgrade vShield Manager.
Follow the procedure in the vShield Quick Start Guide. After this upgrade completes, vShield Manager
notifies vCloud Director that it has a new version. It can take several minutes before vShield Manager
sends the notification and vCloud Director processes it.
