<div>Okay so I have migrated my CCM 4.1.3 to CUCM 7.0.2 and finally got teh licenses to move onto the new hardware, so I have my old production Cluster (4.1.3) and the new shiny toy (7.0.2) which is in my lab, but only one Unity server. </div>
<div> </div>
<div>Since I migrated the old CCM to 7.0.2 I had to change Name and IP on the system to ensure I didn't cause any conflicts.</div>
<div> </div>
<div>Is it possible to run both clusters on on Unity server?</div>
<div> </div>
<div>My concern is that both clusters have the same exact extensions and locations...</div>
<div> </div>
<div>So when I move extension 8801 from Cluster_Old to Cluster_New the gateways (H323) are still there, and an inter-cluster trunk keeps the calls a flowing. Will Mailbox 8801 be accessible after this move?</div>
<div> </div>
<div>My hope is that I can run two Call Managers on one Unity server. What sort of issues can I expect with this line of thought?</div>
