Performing the Actual 9.0.5 Upgrade
Performing the actual software upgrade involves rebooting the appliances and then running the new upgrade 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.
Depending on your upgrade paths, you can either:
Upgrade the Grid to a new release immediately or
Schedule the upgrade. Before you schedule an upgrade, ensure that you understand the limitations, as described in Managing Upgrade Groups.
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.
The NI database upgrade might be time-consuming, with a standard upgrade taking up to 20 minutes, and for larger setups, it can exceed this timeframe.
After a NIOS upgrade, under certain scenarios, Grid replication for some dual-mode Grid members running Subscriber Secure Policy (SSP) takes place using the IPv4 protocol and not the IPv6 protocol.
NIOS restricts you from creating or deleting a network view when the upgrade of a Grid is in progress. Perform these operations after the entire Grid has been upgraded.
