Code upgrade from 11.6 to 12.1.1 HF1

Hi Thiyagu,

1- After choosing the image from the image list and install, Does the system do the self evaluation and choose the correct HF version?

When you navigate to "System ›› Software Management : Hotfix List" you need to select which HF you want to install (sure you need to upload it before) then when you click on "Install" it will only show you boot locations (partitions) that has already the base image installed.

Or 2- Do I need to install the HF from the HF list of the system once after the image installation? If this is the case does the current HF installed on the system will support new image?

You should first finish the base image install, then proceed to the HF install. Each base image has its own HFs. So base image 12.1.2 has different hotfixes from 11.6.1. You need to connect to https://downloads.f5.com to see available HFs for each version.

Hope it helps

Regards
