<p class=MsoNormal>Hi All<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I have a customer who is running Unity 5 with Exchange 2003
Unified messaging, they have built a new separate exchange 2007 cluster and
co-existed it within the same organisation as the Ex 2003 and they are hoping
to migrate users in a staged fashion.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Is it going to be possible to add another message store to
Unity and have users on both clusters or will they have to migrate all of the
users in one go and then re run the Message Store Wizard to change the Partner
server to 2007.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Just wondering what the best options are to tell this
customer as they have already migrated some users without thinking about the
Unity implications.<o:p></o:p></p>
