<br><b>Upgrade tasks:</b><br>1. Backup the BARS<br>2. Install and run the Upgrade Utility all both PUB and SUB<br>3. Install and run the DMA on the PUB<br>4. Install CUCM 7.x<br>5. During the installation process of CUCM 7.x, provide the DMA file<br>

<br>Can someone comment to their experience of upgrading CM 4.x to CUCM 7.x?<br><br>Thanks<br>
