So I've noticed that the name of an Instant image comes with 2 names of versions, like 5.0.3.0-1.0.0.X or 6.2.1.0-3.3.0.X for an example. What does that mean?
That OS for the actual IAPs , when you have IAPs setup as standalone (not RAPs or Campus APs) you can upgrade the image
Does that mean that the instant image 1.0.0.X can work with a 5.0.3.0 controller as a minimum?
I believe that in order for you to do this you need to have on your controller AOS 6.1.4.x or 6.2.x
The 1.0.0.x is the minor version of 5.0.3.0-1.0.0.x not an actual range
