Developed under SP2 - Run under SP3

I have an MFC application developed under Windwsow XP professional SP2.
The application is installed and run on a Windows Embedded standard image (which is SP3).
Are there any risks mixing SP2 with WES ?
My application deals with UDP\TCP communication and GUI.
It does not deal with security issues.

Thanks.

It doesn't matter under what OS it was developed. You only need to have the appropriate dependency DLLs (such as CRT, MFC, etc.) on the target machine.
