Stability release vs Newer releases on ICX 7150 48 & 12 p switches

[kringnalda]

Hello everyone,

I need some advice on upgrading the firmware on my ICX switches (ICX 7150-48P and ICX 7150-12P). I’d like to make use of the new web GUI, as the old GUI is very dated and (seemingly) more limited feature-wise. I also believe there are some syntax differences between the two major versions (08 and 09)  

I know how to update our firmware, and have done it on several switches already, but I see that the recommended “stability” firmware for the ICX 7150 series is still 08.0.95s on the Ruckus download page.

What I’m unclear about is:

1. Are there any risks or known issues with upgrading the ICX 7150-48P and 7150-12P beyond 08.0.95s in order to get the new GUI?
2. Is there a specific target firmware version that’s considered safe/stable for these models that also includes the new GUI?
3. Are there any special caveats or upgrade path requirements I need to follow for these particular models?
   
   
4. This issue arose when I was able to update some of our 7150's to SPR09010k.bin, and it worked on some but returned a "This image version is not allowed on this unit/stack, please refer to the release documentation" on others.

I just want consistency across all our devices with the least amount of stability, security, and modern features sacrificed.

Thanks in advance for any help or pointers!
