Can we use BO4 universe on BO XI 3.1

Hello,

We use BO XI 3.1, we acquired a new application with some basics reports delivered on BO4 universes. Could we use these universes on our BO XI 3.1 ?

In addition, i shall add that we still use BO XI 3.1 because we have not been able to migrate our reports (almost 80% of existing reports) build with "SQL à la carte" method  on BO4.

Thanks & Regards,
