This section provides instructions for upgrading the vCloud Director from version 8.10.1.1 to 9.1.0.3. The vCloud Director installer verifies that the target server meets all upgrade prerequisites and upgrades the vCloud Director on the server.
Prerequisites
-
Verify that you have superuser credentials for the servers in your vCloud Director server group.
-
Verify that the vCloud Director database, vSphere components, and the NSX components are compatible with the new version of vCloud Director.
-
Verify that all ESXi hosts are enabled. Starting with vCloud Director 9.1.0.3, disabled ESXi hosts are unsupported.
-
Take a backup or snapshot of the vCloud Director cells before upgrading them.
-
Back up your existing database before you upgrade it. Use the backup procedures that your database software vendor recommends.
