Upgrading NIOS Software

Will see Upgrading NIOS Software in this post.

Before upgrading do the pre-implementation things for safer side mentioned below.

Check the current version of Infoblox execute below command in web console

admin> show version

Check the license using below command in web console

Note: If the NIOS holding temp license, it’s not advisable to upgrade the Version. It will lead to lose the GUI

https://support.infoblox.com

Click on download tab and you will get next screen. From there select “NIOS Archives (.BIN/2 files)”

Step 2:  

             Once selected “NIOS Archives (.BIN/2 files)” from the dropdown list, next click on “Available for download” button
