When planning your upgrade, a good place to start is the Downloads section on the Infoblox Support sitehttps://support.infoblox.com. Here, you can review the downloads that are currently available and obtain the corresponding release notes for each version that you may be considering. In general, Infoblox recommends that you upgrade to one of the newest versions of NIOS available at the time of your upgrade.
To help with identifying a specific release that you may want to upgrade to, it is helpful to review the release notes for details in the different versions of NIOS that are available, including:
