Upgrade Process

VMware Live Cyber Recovery provides frequent software upgrades each year.

Before the Upgrade

Before a VMware Live Cyber Recovery upgrade, you receive a series of email notifications from VMware support, starting two weeks before the upgrade. You then receive notices at one week and then 24 hours before the upgrade, so you have plenty of time to prepare for the upgrade.

The email notifications specify the maintenance timeframe of your upgrade, which can be a roughly eight hours. The software upgrade takes about 30 minutes to complete during the maintenance timeframe.

Before the upgrade window starts, make sure you commit all recovery plans and stop any running plans. VMware Live Cyber Recovery software cannot upgrade if any recovery plans are uncommitted or running. You also cannot start any failover operations during the upgrade, or the upgrade fails. Software upgrades cannot run if a recovery plan is in the middle of a failover operation or if a plan is running.

During the Upgrade

All of your users must log out of VMware Live Cyber Recovery during the upgrade. If you are logged in and attempt a failover operation, the VMware Live Cyber Recovery UI displays an error message that an upgrade is in progress, and the system prompts you to try again later. The VMware Live Cyber Recovery UI logs out users until the upgrade is complete.

During the upgrade, it might be possible to log in to the VMware Live Cyber Recovery UI. If you log in before the upgrade is over, the overall system health status shows as Unknown and the Topology map icons temporarily disappear then reappear, which is normal and expected behavior.

After the Upgrade

After the maintenance timeframe is over, you can log in and begin using the service.
