A while back I started upgrading some of our WAAS 274/574 devices and once I got halfway through I relized I was on the wrong path to get the devices to accelerate and compress Native ICA for our Citrix sessions.
So Currently I have half our devices at 4.3.3c and the other half at 4.4.7
So my questions are....
What is the latest greatest version that I should be at for Native ICA Acceleration?
What is the best upgrade/downgrade path I should take to get there?
It is recommended/required to run 4.2.1 (or a later version) before you install Version 5.3.1
You cannot upgrade from 4.0, 4.1, or 4.2 to 5.3.1 since it is NOT supported
Here you have a link about it:
Please see the hardware specifications
Hope this helps!
