So far, I can't understand clearly if

Zimbra 7 + Bes 4.1 enterprise

is possible or not.

I've also read in another forum that license keys from 4.1 works with 5, but I can't find any info on Rim website neither a download for the 5

Anybody has already attempted an upgrade? otherwise I'll be stuck with zimbra 6 because I really don't want to upgrade the BES for 2k!!!
