I have a customer that has the following environment:<br><br>* CallMananger 4.1(3) running on two identical MCS-7835-H1<span class="content">-IPC1</span>. IPCC 4.0(4) also runs coresident on the Publisher.<br>* Unity UM 4.0
(3) running in a failover configuration on a <span class="content"> as the primary </span><span class="content">MCS-7835H-3.0-ECS1 </span><span class="content">and a UNITY-SVR7837-1A as the secondary.<br><br>We would like migrate to CallManager
6.0 and Unity 4.2, while replacing the Unity hardware and ordering a new standalone UCCX server at the same time. In order to have the least impact on up time we thought it would be ideal to install the CallManagers onto new hardware. What would be the best way to achieve this. I know that I should order an ECS1 server for the new Unity boxes, but these are probably the servers that I will actually end up using for the CallManagers. I would like to retask the two MCS-7835-H1-IPC1 servers as the Unity servers after the CallManagers have been upgraded, but I'm not sure where I'm left from a licensing standpoint. Will I be able to obtain and use a Unity platform preparation disk on these servers? Would these be TAC supported? Any insight is appreciated.
<br><br>Thanks,<br>Adam<br><br><br></span>
