Online upgrade is available only for VCS. If you have Storage Foundation, SFHA, SFCFSHA, or any other solution with VxVM and VxFS installed, then the online upgrade process is not supported.

The non-Veritas applications running on the node have zero down time during the online upgrade.

VCS does not monitor the applications when online upgrade is in progress.

For upgrades from VCS versions lower than 6.1, upgrade the CP server before performing the online upgrade.
