You can upgrade a single cell by running the vCloud Director installer without command options. Before you restart an upgraded cell, you must upgrade the database schema. You upgrade the database schema after upgrading at least one cell in the server group.
You can use the vCloud Director installer for Linux to upgrade a vCloud Director installation that consists of vCloud Director appliances or vCloud Director installations on a supported Linux OS.
For a multi-cell vCloud Director installation, instead of manually upgrading each cell and the database in a sequence, you can Perform an Orchestrated Upgrade of a vCloud Director Installation.
Verify that your vCloud Director database, the vSphere components, and the NSX components are compatible with the new version of vCloud Director.
If your existing vCloud Director installation uses an Oracle database, verify that you migrated to a PostgreSQL database from vCloud Director version 9.1. See the Workflow for Upgrading a vCloud Director Installation with an Oracle Database.
Verify that you have superuser credentials for the servers in your vCloud Director server group.
If you want the installer to verify the digital signature of the installation file, download and install the VMware public key on the target server. If you already verified the digital signature of the installation file, you do not need to verify it again during installation. See Download and Install the VMware Public Key.
Verify that you all ESXi hosts are enabled. Starting with vCloud Director 9.5, disabled ESXi hosts are unsupported.
For more information about managing a cell, see the cell management reference in the vCloud Director Administrator's Guide .
From an upgraded vCloud Director server, you run a tool that upgrades the vCloud Director database. You must not restart any upgraded vCloud Director server before upgrading the shared database.
After you upgraded all vCloud Director servers in the server group and the database, you can start the vCloud Director services on all cells.
You can Upgrade Each NSX Manager That Is Associated with an Attached vCenter Server System, after which you can Upgrade vCenter Server Systems, ESXi Hosts, and NSX Edges.
