Before upgrading, Infoblox recommends that all members in the Grid be connected to the network and operating normally. If one or more members are offline when you upgrade the Grid, they automatically receive the distributed software and upgrade when they join the Grid or come back online.

The appliance uploads the file and displays the status of the upload in the status bar. You can click the Stop icon in the status bar to stop the upload. Ensure that you do not navigate away from the Upgrade tab until after the upload is complete. Otherwise, the upload process stops.

Note When you upload the NIOS software upgrade to an HA Grid Master, only the active node receives the software. The passive node does not. Therefore, if the Grid Master fails over before a distribution starts, you must upload the software again. If you do not, the distribution fails because the new active node does not have the uploaded software. |
...
Performing a software upgrade involves rebooting the appliances and then running the new software. Essentially, each appliance switches between the two software partitions on its system, activating the staged software and saving the previously active software and database as backup.

Note Before you upgrade the software, Infoblox recommends that you back up the current configuration and database. For information, see Backing Up and Restoring Configuration Files. |

After the Grid Master has been upgraded, you can choose to immediately upgrade a specific member that has not been upgraded yet. This function is available only for scheduled Grid upgrades from NIOS 6.4. 0 to a later release. You can upgrade a single member only when the Grid upgrade is paused, and you cannot upgrade the Grid Master, reporting appliance, and an offline member. Once the member has been manually upgraded, the appliance skips this member when its scheduled upgrade time is reached.

Reverting a Single Member
During an upgrade from NIOS 6.4.0 to a later release, you can revert a specific member that has already been upgraded and is within its revert time window. The revert single member feature is useful when you want to troubleshoot issues, such as service outages, on a specific member after it has been upgraded. You can revert a member only when the Grid upgrade is paused, and you cannot revert the Grid Master, reporting appliance, and an offline member. If the upgrade is paused and you have reverted a member in an upgrade group that has already completed the upgrade, you must move the member to another upgrade group that has not been upgraded before you can proceed with the upgrade.
Once a member is upgraded, the appliance starts counting down and displays the time that is left for you to revert this member. You can revert the member before the revert time window expires. The default time window to revert a member is 24 hours. You can view the time that is left to revert the member in the Member List view, as described in Grid and Memeber status below. You can also use the CLI commands set default_revert_window to configure the default revert time window for the Grid. For information about this command, refer to the Infoblox CLI Guide. Once a member exits the revert time window, you must revert the entire Grid in order to revert the member.

Note You may potentially lose some data when you revert a member. The appliance keeps information about DHCP leases and DNS records intact. |

When an upgrade starts, Grid Manager checks if the nodes of an HA Grid Master have the same NIOS software version on their alternate partitions. If they do not have the same software version, the upgrade process stops. Grid Manager displays an error message and if it is a scheduled upgrade, Grid Manager deactivates the schedule as well. Otherwise, the upgrade process continues.
