Hi, thanks for asking here.
Since we haven't tested (officially, anyway) the GIS Integration on Apps 10 on the version you are asking about, I think you need to test on your own, and see.
My guess is it will work fine, and I base that on more or less 10 years of working with our GIS Integration and ArcGIS. I cannot remember a single incident that we have identified as being a problem with a newer version of ArcGIS Server.
But we cannot officially say that unless we have actually tested and, as Stefan hinted at in his reply to you, we would probably test on 11.x rather than the 10.x track.
Good luck!
Thanks Mathias. Do we still have provision to get Test Licenses / Trial License for the Arc GIS integrator?
BR,
Ritz.
That's outside my area of expertise I'm afraid.
Perhaps you can use an internal test environment and connect to the customer's ArcGIS Server, if they can expose it to you via VPN or on the public internet?
