2 After you have upgraded vShield manager, you must upgrade all vCenter and ESX/ESXi hosts before you
upgrade the vShield Edge appliances that the upgraded vShield Manager manages.
Upgrade vCenter, ESX/ESXi Hosts, and vShield Edge Appliances
After you have upgraded vCloud Director and vShield Manager, upgrade the vCenter servers and ESX/ESXi
hosts attached to your cloud, then upgrade vShield Edge appliances on upgraded vCenter servers.
Procedure
1 Upgrade the vCenter server.
See the vSphere Installation and Setup Guide.
2 Refresh the vCenter server's registration with vCloud Director.
a In the vCloud Director Web console, click the Manage & Monitor tab and click vCenters in the left
pane.
b Right-click the vCenter Server name and select Refresh.
c Click Yes.
3 Upgrade each ESX/ESXi host that the upgraded vCenter server supports.
See the vSphere Installation and Setup Guide. For each host, the upgrade requires the following steps:
a In the vCloud Director Web console, disable the host.
On the Manage and Monitor page, click Hosts, then right-click the host and select Disable Host.
b Use vCenter to put the host into maintenance mode and allow all the virtual machines on that host
to migrate to another host.
c Upgrade the host.
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.
d Use vCenter to reconnect the host.
e Upgrade the vCloud Director host agent on the host.
See "Upgrade an ESX/ESXi Host Agent" in the vCloud Director Administrator's Guide.
f In the vCloud Director Web console, enable the host.
On the Manage and Monitor page, click Hosts, then right-click the host and select Enable Host.
g Use vCenter to take the host out of maintenance mode.
4 Upgrade all vShield Edge appliances managed by the vShield Manager on the upgraded vCenter server.
Use the vShield Manager user interface to manage this upgrade.
NOTE If you use the vCloud Director Web console or REST API to reset a network that vShield Edge
protects, this upgrade occurs automatically. Using the vShield Manager user interface to manage the
vShield Edge provides better administrative control over the upgrade process and related network
downtime.
