You can upgrade to a later release on a standalone Command Center appliance or an HA pair. To upgrade a standalone node, first stop Command Center, upgrade the software, and then start Command Center. To upgrade an HA pair, run a script available in the /opt/Citrix/Citrix_Command_Center/bin
directory. Before running the script, make sure that you know the path to the service pack for upgrading the appliance.
Note: You cannot downgrade a Command Center appliance.
