Product change devexpress 12.1 to 14.2 script not run

Just recording and plying is good for a start. But before going for record thounds of test cases you have to
build robust test frame-work. what I mean is way of handling errors, way to handle change of application and
reuserbility of test scripts.

what you could do now is analys errors you got, and try to write tests which can handle those next time.
You can get help for specific problems / errors from this forum.
