Transport from BO v.4.1 to BO v.4.0 SP5

Hi all,

We are thinking on upgrading our BO version from 4.0 (SP5) to version 4.1.

Our main doubt in order to keep on going with the upgrade is that, once we have upgraded BO Development environment from 4.0 SP5 to 4.1, if we modify any webi and transport it to Test environment (which will still be in version 4.0 SP5), would the transport fail or would webis be transported incorrectly?

Thanks
