EV migration query

hi

I am after some advice. We are planning an AD domain migration. Currently the test lab is EV 9.0.3 and PROD is 9.0.2.

Does anyone think there would be an issue migrating from 9.0.3 (W2k3 AD) to 9.0.2 (W2K8 AD) in a test lab?

Apart from the obvious solution of re-building the test lab to 9.0.2 would a 9.0.3 > 9.0.2 AD migration work?

thoughts?

thanks
