A governed, automated approach to moving from Cisco Unified Communications Manager to Webex Calling with greater visibility, less rework, and more predictable execution

Author: Andrea Gasior, Chief Revenue Officer, Akkadian Labs

Are we truly ready? 

It is the most important question in any migration—and often the hardest to answer. 

Long-running Cisco Unified Communications Manager (CUCM) environments do not remain perfectly standardized. They evolve. Business units make local decisions. Temporary workarounds become permanent. Numbering plans drift. Legacy devices remain in service. Call-routing logic overlaps. Exceptions accumulate, and some of the people who understand why may no longer be with the organization. 

None of that is unusual. But every unseen exception can become a source of delay, rework, or user disruption when the organization moves to Webex Calling. 

I look at migration technology through two practical questions: Does it improve the customer’s ability to achieve and verify the intended outcome? And does it make delivery more efficient for the customer and the partner? 

Advanced Migrate for Webex was built to address both. 

It brings readiness assessment, migration planning, validation, governed provisioning, and real-time execution visibility into one enterprise-scale workflow. The objective is not simply to automate more tasks. It is to help teams make better decisions earlier, execute with greater control, and verify what happened at every stage. 

Because efficiency without governance can simply move risk faster. And assurance without automation can be slow, manual, and difficult to scale. 


Start with Evidence 

Before anything is provisioned into Webex Calling, Advanced Migrate for Webex analyzes the source environment. Teams upload a CUCM configuration export or Unity Connection voicemail database, and the platform evaluates users, devices, lines, hunt pilots, call routing, and other critical configuration elements. 

More than 110 automated readiness checks identify potential issues. Each finding is tied to the affected object, classified as a Blocker, Warning, or Informational item, and paired with recommended remediation guidance. 

The result is an evidence-backed answer to three questions: 

•  What can move? 

•  What needs attention? 

•  What should be fixed first? 

This is where migration efficiency begins. Teams can prioritize remediation before dates and delivery resources are locked. Leaders gain a clearer view of readiness. Customers and partners work from the same evidence instead of reconciling separate spreadsheets, scripts, and institutional knowledge. 

For customers, that supports more defensible planning and fewer late-stage surprises. For partners, it creates a repeatable readiness methodology that can be applied consistently across engagements.


Turn exceptions into a governed migration plan 

Advanced Migrate for Webex lets administrators organize work into projects and batches, then curate exactly what moves in each wave. Organizations can structure the migration around a pilot, site, business unit, geography, department, or another operating priority. Teams can select users, lines, shared lines, workspaces, speed dials, busy lamp fields, caller ID, line labels, call forwarding configurations, and other dependent objects. 

The business does not have to conform to the migration tool. The migration tool supports the business strategy. 

The platform also uses AI-assisted suggestions to help clean and normalize source data before it reaches Webex Calling. Each suggested change remains reviewable, auditable, and reversible, preserving administrator control. 

That matters because a migration is one of the few opportunities to improve an environment, not simply reproducing years of accumulated complexity in the cloud. A more consistent destination reduces cleanup during delivery and creates a stronger operating foundation after cutover.


Build outcome assurance into execution 

Advanced Migrate for Webex applies discipline throughout execution. 

A pre-execution validation stage identifies invalid data before anything is provisioned into Webex Calling. During the migration, objects are created in dependency-aware order, beginning with phone numbers and continuing with the users, workspaces, and devices that rely on them. If a foundational object cannot be created successfully, the process stops rather than continuing with incomplete dependencies. 

The platform supports migration waves of approximately 100,000 entities, with automatic retries, safe recovery from interruptions, rollback capabilities, and real-time status tracking. Administrators can see what succeeded, what requires attention, and the reason behind each result. 

This turns exceptions from cutover surprises into visible, actionable work. It also creates a durable record that teams can use to validate the outcome of each wave before moving to the next. 


Efficiency that compounds for customers and partners 

The operational benefits are straightforward: faster preparation, less avoidable rework, controlled phased execution, clearer accountability, and greater visibility from assessment through migration. 

But the value compounds when customers and partners work from the same governed process. 

Customers gain a more predictable path to Webex Calling, with the flexibility to sequence the move around business priorities and the evidence to support decisions along the way. 

Partners gain a standardized delivery model that can scale across customers, engineers, and projects. Less time is spent on repetitive discovery, manual reconciliation, and avoidable correction. More time can be directed toward architecture, customer guidance, and the higher-value work that improves the engagement. 

The commercial impact follows the operational improvement: more predictable delivery, better use of specialized resources, stronger customer trust, and a foundation for long-term services rather than a one-time migration project. ry. 


The migration is not the finish line 

Most migration tools are designed to complete a project. Advanced Migrate for Webex is part of a platform designed to support what comes next. 

After the move to Webex Calling, organizations can continue using the Akkadian Platform to manage user changes, provisioning, licenses, and governance across the collaboration lifecycle. The same principles that improve migration, automation, visibility, control, and auditability can be carried into ongoing operations. 

Because collaboration does not operate in isolation, the Akkadian Platform also supports integrations across the wider enterprise ecosystem ncluding ServiceNow, Active Directory, Microsoft Entra ID, Intrado, ISI, Mobile Heartbeat, and other business-critical systems. These connections help extend governed automation across the identity, service management, emergency response, call accounting, and critical communications systems that shape the user lifecycle. 

That is an important distinction. The migration is not an isolated event. It is a transition into a more connected, governed operating model.


A better standard for Webex migration 

Organizations moving from CUCM to Webex Calling do not need complexity; they need a more reliable path from readiness to result. 

Advanced Migrate for Webex helps teams prove readiness, expose exceptions, structure the migration around the business, validate before changes are made, orchestrate execution at enterprise scale, and verify the outcome of every wave. 

That is how migration efficiency improves without sacrificing control. It is also how outcome assurance becomes practical—not through promises, but through evidence, governance, and visibility.
