Health Tech Datacentre Refresh: 11 Sites, Zero Disruption

About the Client

A global health technology company producing diagnostic imaging, patient monitoring, and connected care systems, operating research, manufacturing, and commercial facilities across North America and Europe. Health technology organizations run datacentre infrastructure that supports both corporate operations and connected clinical products. Refresh activity must be sequenced with unusual care the systems being touched may sit in the service path for products deployed in hospitals. Infosys, as Systems Integrator, holds the client relationship and overall programme governance, and engaged Teceze as its specialist delivery partner for this dual-continent infrastructure modernization.

The challenge

Refreshing Datacentre Infrastructure in the Service Path of Connected Health Products

The constraint: Clinical-adjacent service path sensitivity, 11 sites across two continents, a compressed three-month window

The client’s datacentre infrastructure supports both corporate operations and connected clinical products deployed in hospitals. Refresh activity must be sequenced with unusual care—the systems being touched sit in the service path for products that may be deployed in hospital environments. The programme required executing 11 site refreshes across North America and Europe within three months, replacing 100+ network devices and servers while maintaining service continuity for infrastructure supporting connected health systems.

Our approach

Survey-Driven Dual-Region Refresh Model Combining Pre-Visit Assessment, Parallel Regional Execution, and Continuity-Aware Sequencing

Teceze implemented a structured refresh programme prioritizing pre-visit survey accuracy, parallel dual-region execution, and service continuity protection. The approach combined site survey preceding refresh activity at every location capturing rack layout, power, cabling, and dependency detail, parallel North American and European site execution under a single programme plan enabling 11-site completion in three months, combined network device and server refresh workstreams at each site halving change windows per location, and continuity-aware sequencing accounting for service dependencies to ensure infrastructure supporting connected health products was never left without a supported path during change. This model transformed a compressed multi-continent refresh into controlled, parallel execution with service continuity maintained throughout.

From challenge to transformation, the solution included:

Survey-Led Refresh Planning

A site survey preceded refresh activity at every location, capturing rack layout, power, cabling, and dependency detail so the refresh plan was built from verified conditions rather than existing documentation that was often incomplete or outdated, ensuring first-visit success.

Parallel Dual-Region Execution

North American and European sites were addressed in parallel under a single programme plan, making an 11-site refresh achievable within a three-month window through coordinated regional delivery teams.

Combined Network and Server Workstreams

Network device and server refresh were delivered together at each site rather than as separate visits, halving the number of change windows required per location and reducing aggregate site disruption.

Continuity-Aware Sequencing

Refresh sequencing accounted for service dependencies so infrastructure supporting connected health products was never left without a supported path during the change, protecting dependent clinical systems from interruption.

Governance and Reporting Cadence

Operational transparency and stakeholder alignment are critical to program success. A layered governance model keeps refresh progress and service continuity visible across both regions:

Cadence	Forum	Focus
Daily	Site Refresh Operations Review	Open change windows, site-level status, escalations
Weekly	Regional Progress Review	Refresh pace by region, dependency verification status, upcoming schedule
Monthly	Programme Governance Call	Overall completion rate, continuity incident review, schedule risk
Programme Close-Out	Final Governance Review	Full refresh completion across all 11 sites, SLA attainment, lessons learned

The Results

11 Sites Refreshed Across Two Continents with Zero Service Disruptions

11Sites Refreshed

100+Devices Replaced & Validated

3 monthsCompressed Timeline

11Sites refreshed across North America and Europe simultaneously within the three-month programme window

100+Network devices and servers replaced and validated at each location with zero equipment issues — an annualized delivery rate of approximately 44 sites and 400 devices per year

3 monthsCompressed timeline achieved through dual-region parallel execution and combined network/server visits, cutting change windows by 50% per site, with zero disruptions to connected health products

Why it matters

Multi-continent infrastructure refresh with service continuity sensitivity represents unique execution complexity: compressing 11 sites into three months requires parallel regional execution, mixed device classes demand different handling and validation approaches within the same site visit, and service continuity protection for connected health products cannot be compromised by infrastructure changes.

Completing an 11-site dual-continent refresh in three months with an annualized delivery rate of 44 sites and 400 devices while maintaining service continuity demonstrates exceptional programme discipline and logistics execution.

What the client says

“Executing an 11-site datacentre refresh across two continents in three months while protecting connected health systems is extraordinarily complex. Teceze’s survey-driven approach meant every site was planned precisely before we showed up. Parallel regional execution kept momentum going. Combining network and server refresh cut our change windows in half. Zero service disruptions to our connected products—that’s what matters. Their execution demonstrates they understand what happens downstream when health systems are involved. We’re now confident they can scale this approach as we modernize additional datacentres globally.”
