The old cluster has security turned on (CTL Client an E-Token). What makes more difficult is, we have to use the old Publisher as an centralized TFTP Server for both, the old 7.1.5 and the new 8.6 Cluster.<br><br>I thought it should be possible by doing it this way:<br><br>- Define the 8.6 TFTP-Server as alternate TFTP on the old Server<br>- Run the CTL-Client on the old Cluster and put the new TFTP Server in the CTL File<br>- Run the CTL-CLient on the new Cluster and add the old TFTP Server<br>- Configure the new Cluster with all Phones<br>- Delete the Phones on the old Cluster (Change MAC Add.)<br><br>But in this scenario the Phones would not register to the new Cluster? <br><br>Now i am looking for a strategy to configure it correctly.
