Hi All,<br><br>I will be doing an upgrade of CCM 4.1x to CUCM 7.1x, which I have never done before. I wanted to find out what experience people have had with this upgrade in the past. He have new hardware for CUCM 7.1x and process will be running the BAT tool, installing the CUCM 7.1x with a new IP address, configuring a QSIQ trunk from old and new and updating the remote gateways with the updated CUCM IP.<br>
<br>I want to find out if there's anything I should know before doing the upgrade, and if the BAT tool will export all the data to be then imported to the new server.<br><br>Thanks for all the help and feedback.<br>
