F5 Upgrade

Hi All,

Hope you all are safe and doing well!

I am planning to upgrade F5 from 15.1.2.1 to 15.1.3.1, so in order to get the .iso file i use below link and downloaded 1st File (BIGIP-15.1.3.1-0.0.18.iso)

https://downloads.f5.com/esd/eula.sv?sw=BIG-IP&pro=big-ip_v15.x&ver=15.1.3&container=15.1.3.1&path=&file=&B1=I+Accept

Can you please let me know if it is correct way to download .iso file to upgrade the F5.

Note :- I have hardware module of F5.
