Is it just me, or the old firefly landing page, download wise, isn't rendering the two tabs of 'Software' and 'Documentation' ?
Firefly has reached end of support and is no longer available. Please use vSRX.
Ok.. and in my ignorance.. and unware if there is a multi-hop upgrade process or not..
I.e. A 12.# versioned firefly OS can go directly to a vSRX OS version and I won't need to perform any multi-hop/interim upgrade that required one to gather firefly software from the aforementioned download page which is just foreever/infinite loop styling cycling and rendering images or doco..
You will need to install a new installation of vSRX and migrate configuration. There is no inline upgrade path.
