F5 ASM upgrade

Question

As it is aware that version (BIG-IP 15.1) of the existing software used on our F5 devices ( i2600 ) will expire after year 2024. We are planning software upgrade to keep equipment in our environment are actively supported by product vendor.

When checking from F5 web site, there are two upstream version 16.1 and 17.1 respectively. I would like to check ( in terms of viability and stability and the support of JSON format for ASM policies ), may I know which version (16.1 or 17.1) would be recommended? Thanks.

If you plan to replace your hardware any time soon, you should upgrade to 17.1. The new rSeries appliances are supporting only 15.1 or 17.1. If not, upgrade to 16.1, I had some severe issues with ASM on 17.1 in the past.

BIG-IP 16.1.x is EoSD on July 31, 2025. (https://community.f5.com/t5/technical-forum/f5-asm-upgrade/m-p/326495) Hardware i2600 is EoSD on Jan 1, 2027. (https://my.f5.com/manage/s/article/K000133583). You have some runway on the hardware and software should you go to BIG-IP 16.1.x for now, especially if you are working with ASM policies.
