ArCGIS Server 10.1 and Older ESRI Flex Library

I have a FLEX application created with the 2.2 ESRI Library. Will my application break if I transfer it to ArcGIS Server 10.1?
Thanks

Probably not.

The only forward-compatibility issue in the Flex API I'm aware of is using 1.x to connect to a tiled map service that is from a 10.1 service, but if you are using 2.2 then you should be fine.  However, this is not a use case we have tested extensively.

Thank you Bjorn. I will transfer the application and will post again if any issues arise! Cheers!
