In summary

A migration to Genesys Cloud CX is a chance to move your contact centre onto a cloud-native platform without losing what already works. QVCCS plans and delivers migrations from Avaya, Cisco UCCE and UCCX, Genesys PureConnect, Genesys Engage, Mitel, NICE and other on-premise or hosted platforms. Certified specialists from our own bench run detailed discovery, helps you decide where to keep parity and where to transform, then designs, builds and tests the new environment. We manage phased cut-over, number porting, recordings and data migration and training, so customers keep getting through.

Our seven stages applied to migration, each closed by a quality gate, so risk falls as the programme moves forward.

01

Planning a migration to Genesys Cloud CX

A migration to Genesys Cloud CX moves the system your customers depend on every day, so it has to be planned as a business change rather than a technical swap. Many established contact centre platforms have served their owners well for years, and have accumulated routing rules, announcements, integrations and reports that reflect a great deal of hard-won operational knowledge. The goal is to carry that knowledge across while gaining the elasticity, continuous delivery and AI capabilities of a cloud-native platform. Our leadership has worked in contact centre technology since 1984, and that long view shapes how we approach every move.

Genesys Cloud is cloud-native and multi-region on AWS, built from elastic, self-healing microservices. That changes how capacity, resilience and upgrades are managed: there is no hardware refresh to plan and new features arrive continuously. For many Genesys customers the timing is also set by the vendor. Support for all PureConnect platforms ended on 31 July 2025, and Genesys has announced end of maintenance and support for Genesys Engage on-premises and subscription products on 31 December 2028, with full-year renewals ending a year earlier. We help contact centre leaders and technical architects build one shared plan around those dates, covering agents, networks, identity, integrations and change control, before the first workstream starts.

02

Discovery and the parity versus transformation decision

Discovery is the most valuable phase of any migration. Our consultants and architects examine the existing call flows, scripts, queues, skills, schedules, announcements, CTI and CRM integrations, recording and quality processes, workforce management, reports and data feeds, and we run a site, network and telephony readiness survey alongside. We look for behaviour that is not documented anywhere: a holiday rule in an IVR, a database lookup in a routing script, a report a regional manager relies on every Monday. Each item is captured in a migration inventory with an owner, a priority and a target approach, and carried into the Requirements Traceability Matrix, so nothing important depends on someone remembering it during cut-over week.

With the inventory in place, we help you decide journey by journey between parity and transformation. Parity reproduces existing behaviour faithfully, keeping training and risk low. Transformation redesigns a journey to use capabilities such as digital channels, predictive routing, virtual agents or agent assist. Most programmes blend the two: core voice journeys move with careful parity, while selected journeys are transformed where the business case is clear. QVCCS documents each decision with its reasoning, its impact on agents and customers, and its dependencies, so stakeholders can sign off a target design with their eyes open.

A good migration keeps everything your customers value, drops what they never noticed, and leaves room for what comes next.

QVCCS point of view

03

Source platforms, data and number porting

Every source platform has its own concepts, and translating them well is specialist work. Avaya vectors and skills, Cisco UCCE and UCCX scripts, Genesys PureConnect handlers, Genesys Engage strategies, Mitel and NICE configurations all map to Architect flows, queues, skills and routing in different ways. Our architects understand how these concepts relate, and design the Genesys Cloud CX equivalent around the outcome each one delivers rather than copying its structure line by line. That keeps the new environment clean, maintainable and ready for whatever you want to add next.

Data and numbers need equal care. Historical recordings may need to remain accessible for compliance, quality or dispute handling, so we agree with you which recordings move, which stay in an archive and how metadata is preserved for search. User, skill and queue data is cleansed and loaded in a repeatable way, often through automation. Telephony is planned with your carriers, covering SIP trunks, number porting windows, interim redirects and emergency calling. Each porting wave is scheduled against your trading calendar so that the busiest days are never the riskiest.

Integrations are often the longest pole in a migration. CTI connectors, CRM screen pops, payment solutions, workforce management feeds and reporting extracts may all depend on interfaces specific to the current platform. We catalogue each one, define its target pattern on Genesys Cloud CX, whether a native integration, an AppFoundry partner app, data actions or bespoke development, and write an interface contract that downstream system owners can review. Where both platforms must run side by side for a period, we design how the two will coexist, including transfers between them, so customers and agents experience a single contact centre throughout.

04

Who runs your migration, and what catches programmes out

A migration needs every discipline at once, so we muster a multidisciplinary team from our own bench and run it as one programme. A Programme Manager runs governance, the RAID log and the wave plan. An Enterprise Solution Architect sets the target architecture and a Solution Architect owns the HLD, LLD and interface control documents. A Senior Business Consultant / Business Analyst leads discovery and the migration inventory. Senior Developers build flows, data actions and configuration as code with CX as Code; an IT Systems, Telecoms & SIP Engineer plans trunks and porting; testers and a Trainer prepare the cut-over. What is distinctive here is the wave: each move by site, team, channel or number range has its own rehearsed runbook, entry and exit criteria, test calls, rollback plan and a remote go-live command centre staffed by our engineers.

Several things catch migration programmes out. Reports rarely match at first, because the old and new platforms define measures such as service level or abandonment differently, so we reconcile definitions before go-live and warn leaders which figures will move for that reason alone. Legacy changes made during the programme quietly invalidate the inventory, so we agree a change freeze, or a process for mirroring essential changes in the new design. Agent readiness is easy to underestimate: browsers, headsets, home-worker networks and single sign-on all need checking before the first wave. Contract dates for legacy maintenance, carriers and licences should line up with the wave plan, so you are not paying twice for longer than necessary, nor left without support during a delayed wave.

05

After go-live: stabilise, optimise and evolve

Migration is the beginning of life on Genesys Cloud CX, not the end of a project. Once the last wave has moved, QVCCS helps you decommission legacy components safely, close out remaining actions and baseline performance on the new platform, so later improvements can be measured against a fair starting point. Support then follows your new consumption model: we work inside your provider's service delivery model through managed professional services and expert escalation, or provide SLA-based support where you contract it with us directly. From there we help you build a roadmap: the transformation journeys you deferred, new channels, workforce engagement and AI capabilities, each delivered with the same discovery, design and testing discipline that carried the migration.

Questions

Migration to Genesys Cloud CX: common questions

Which platforms can you migrate to Genesys Cloud CX?

We plan and deliver migrations from Avaya, Cisco UCCE and UCCX, Genesys PureConnect, Genesys Engage, Mitel, NICE and other on-premise or hosted platforms. PureConnect support ended in July 2025 and Genesys Engage premises support ends in December 2028, so timing often matters. Whatever the source, we start with detailed discovery so the design reflects how you work today.

Should we replicate our current setup or redesign it?

Usually a mix of both. Replicating core journeys keeps risk and retraining low, while redesigning selected journeys lets you use cloud-native capabilities where they add clear value. A useful test is whether a journey works well for customers today: if it does, move it faithfully; if it does not, a migration is the cheapest moment to change it.

What happens to our historical call recordings?

That depends on your compliance, quality and retention requirements. Some recordings are migrated with their metadata, others remain in a searchable archive until retention expires. We agree the approach with your compliance and IT teams early, so access to historical recordings is never lost during the move.

How do you avoid disruption during cut-over?

We move sites, teams and numbers in planned waves rather than all at once. Each wave has entry and exit criteria, test calls immediately after the change, a rollback plan and engineers on a live bridge, followed by hypercare until stability is confirmed.
