s it time to plan for an upgrade again? Cisco has announced that the timeframe between major and minor version releases of their Cisco Unified Communication Management (CUCM) application is accelerating. The accelerated time and frequency level of upgrades is pushing businesses to have robust, validated, and "ease of use" processes to perform upgrades. We had a global financial customer request we build a lab environment in the Advanced Technology Center (ATC) to help them perform testing on the software upgrade process for their multiple CUCM clusters.
