Before upgrading
Before upgrading to vSphere 6.0 Update 1, read carefully the KB2124669 article.
Upgrade the vCSA
Since vCenter Server Windows based can be updated simply running the installer, the vCSA appliance requires a different procedure to apply the patch. Full how-to can be found in this post.
Mount the Update 1 ISO file, SSH the vCSA and type the command:
Command> software-packages install --iso
Type yes then press Enter to apply the upgrade.
Reboot the appliance with the command:
Command> shutdown reboot -r patching
After rebooting the appliance, the new build number is 6.0.0.10000.
The vCSA is now updated to latest release.
