Using SAP BI 4.2 client tools with SAP BI 4.1 CMS

Hello,

I would like to know the possible issues when using SAP BI 4.2 client tools with SAP BI 4.1 CMS : what problems could I face, for example, when exporting universes from the Universe Design Tool version 4.2 to the CMS version 4.1 ?

Thank you.
