1. if we migrate to exchange 2010 and keep BES 4.1, will it work? must upgrade to BES 5.0
first as BES 4.1 will not work with exchange 2010!
2. if we will do both, shall BES upgrade be done first? YES
3. Our provider sent us an offer for BESx 5 and said it is the same as BES but for small organizations (we have 40 users).
we found on the net that BESx is free!!! Also, inplace upgrade is not possible from BES 4.1 to BESx 5. What will we
really lose if we go with BESx and is it realy free? Yes its free and yes you lose a lot of IT policy items.
4. will the license cost of upgrading BES 4.1 TO BES 5.0 be as the same as purchasing a new BES 5 licenses? BES CALs are still the same price.
if going free BES/SBE/BPS 4.x upgrade options to BES Express 5.0 - BlackBerry Support Community Forums
if not going free then you need to get the upgrade
