NIOS 9.0.5 is on an average 178% larger than NIOS 8.6 and 67% larger than earlier NIOS 9.0.x versions because of the new features/enhancements (such as Threat Insight). Uploading the .bin file may take a while and if you have set a default session timeout, the session can expire when the upload is taking place in the background. Infoblox recommends that you change the default session timeout setting from 600 seconds to 1800 seconds. You can update the setting in the Security tab > Session Timeout(s) field.
In NIOS 9.0.5, upgrade fails if the listen-on, notify-source, and query-source options are configured with port 53 for both IPv4 and IPv6 addresses.
Accelerated networking can be enabled for NIOS members in Microsoft Azure from version 9.0.5 onwards. This resolves an issue where accelerated networks had to be disabled on NIOS members in Microsoft Azure before upgrading to NIOS 9.0.0, 9.0.1, 9.0.2, 9.0.3, or 9.0.4.
There will be an impact on the CPU and DNS performance when Threat Insight is enabled.
You can only run Threat Insight when a minimum disk size of 250 GB is set on the Grid member; the size includes upgrading with Threat Insight enabled on the member. Failing to do so may result in functionality issues.
If you have used the ZSK or KSK algorithm key size 640 (which is invalid in BIND 9.16), the upgrade may fail.
If the length of the DH key is lower than 1024, upgrade will fail.
