<div>I will be upgrading Unity from 4.0.5 to 5.x in the next couple months.</div>
<div> </div>
<div>is there any problem if the server guys bring up a new exchange 2007 before hand so long as the UM subscribers are not on the exchange 2007 box? or does that screw up everything due to schema, etc.</div>
<div> </div>
<div>If I'm running two exchange 2003 servers and add a 2007 I just don't want it to bring everything else down as far as UM is considered.</div>
<div> </div>
<div>Thanks</div>
