6 Upgrade vShield Manager. All vShield Manager installations registered to this server group must be
upgraded to a version of vShield Manager software that is compatible with the version of
vCloud Director installed by the upgrade. If the upgrade program detects an incompatible version of
vShield Manager, upgrading is not allowed. You must upgrade to the latest version of vShield manager
listed in “Supported Platforms,” on page 8 to use networking features introduced in this release of
vCloud Director. See “Upgrade vShield Manager,” on page 40.
7 Enable user access to vCloud Director.
8 Upgrade vCenter servers and hosts. See “Upgrade vCenter, Hosts, and vShield Edge Appliances,” on
page 40. All vCenter servers registered to this server group must be upgraded to a version of vCenter
software that is compatible with the version of vCloud Director installed by the upgrade. Incompatible
vCenter servers become inaccessible from vCloud Director after the upgrade is complete. See
“Supported Platforms,” on page 8.
Using a Load Balancer to Reduce Service Downtime
If you are using a load balancer or other tool that can force requests to go to specific servers, you can
upgrade a subset of the server group while keeping existing services available on the remaining subset. This
approach reduces vCloud Director service downtime to the length of time required to upgrade the
vCloud Director database. Users might experience some degradation of performance during the upgrade,
but in-progress tasks continue to run as long as any subset of the server group is operational. Console
sessions might be interrupted, but you can restart them.
1 Use the load balancer to redirect vCloud Director requests to a subset of the servers in the group.
Follow the procedures recommended by your load balancer.
2 Use the cell management tool to quiesce the cells that are no longer handling requests and shut down
vCloud Director services on those servers.
NOTE Console sessions routed through a server's console proxy are interrupted when the server shuts
down. Clients can refresh the console window to recover.
See “Use the Cell Management Tool to Quiesce and Shut Down a Server,” on page 35.
3 Upgrade vCloud Director software on the members of the server group on which you have stopped
vCloud Director, but do not restart those services. See “Upgrade vCloud Director Software on Any
Member of a Server Group,” on page 36.
4 Use the cell management tool to quiesce the cells that you have not yet upgraded and shut down
vCloud Director services on those servers.
5 Upgrade the vCloud Director database. See “Upgrade the vCloud Director Database,” on page 38.
6 Restart vCloud Director on the upgraded servers. See “Start or Stop vCloud Director Services,” on
page 32.
7 Upgrade vShield Manager. See “Upgrade vShield Manager,” on page 40.
8 Upgrade vCenter servers and hosts. See “Upgrade vCenter, Hosts, and vShield Edge Appliances,” on
page 40.
9 Use the load balancer to redirect vCloud Director requests to the upgraded servers.
10 Upgrade vCloud Director software on the remaining servers in the group, and restart vCloud Director
on those servers as the upgrades complete. See “Upgrade vCloud Director Software on Any Member of
a Server Group,” on page 36.
