Digital Transformation & Legacy Modernization

Replace spreadsheets, paper and aging systems with modern platforms — without stopping the business. Process automation, cloud migration, monolith-to-microservices. San Jose, CA & Slough, UK.

Modernize how the business runs — without a big-bang rewrite that puts operations at risk.

NHZ Global helps companies and public bodies in the USA, UK and the Gulf move from spreadsheets, paper and aging systems to modern platforms their teams actually use. We have migrated half-million-line monoliths to microservices with zero downtime, re-platformed retail systems for ten times the traffic, and replaced seven disconnected training systems with one. The approach is always the same: understand the operation, deliver value in phases, and never take a working system away before its replacement is proven.

Where we help

  • Process digitization — the workflows still running on email, spreadsheets and paper, rebuilt as software with an audit trail
  • Legacy modernization — incremental migration of old platforms to modern, cloud-native architectures using the strangler pattern
  • Cloud migration and cost engineering — AWS and Azure moves that cut cost and improve resilience, not just relocate the problem
  • Systems integration — ERP, CRM, EPOS, e-commerce, HR and finance systems talking to each other automatically
  • Data and reporting — one source of truth, dashboards for management and automated regulatory reporting
  • Change and adoption — training, pilots and phased rollout so staff come with you

How we run a transformation

  1. Assessment (fixed price, 2–4 weeks) — systems, processes, data, risks and a prioritized roadmap with costs per phase
  2. Quick wins first — the changes that pay back in weeks, to build momentum and fund the rest
  3. Phased delivery — new capabilities land every few weeks alongside the old system until cut-over is safe
  4. Measure — every phase has a number attached: hours saved, errors removed, cost reduced
  5. Handover — documentation, training and your own ownership of code and infrastructure

Frequently asked questions

Do we have to stop using our current system during the migration?

No. We run old and new side by side, moving one function at a time, and only retire the old system when the new one has proven itself in production.

How do you decide what to do first?

By payback. The assessment ranks every opportunity by cost, risk and the value it releases, and the roadmap starts with the fastest wins.

Can you work with our internal IT team?

Yes — most transformations are joint efforts. We can lead, augment or advise, and we hand over fully at the end.

Which cloud do you recommend?

Whichever fits your existing skills, compliance needs and budget. We are experienced on AWS and Azure and will give you a straight comparison for your case.
