Thank you Ashfaq. I have these manuals and I cannot find any information definitively answering my question above on compatibility issues. I am asking if anyone has experienced any issues or a confirmation that there are absolutely no compatibility issues with applications created using Desktop 10 when published to Server v11. My client wants to be reassured before even upgrading the dev server.
I Personally haven't seen any compatibility issue with this upgrades.
IF you Build application on V11 then move to V 10, then there may exists some compatibility issue. But not with your case.
Its always recommended to have latest version as it come up with lots of new features and big fixes.
The Only challenging part here is upgrade. Which can be solved by going through the document I suggest.
Hope it helps.
