Escaping Legacy Lock-In: How AWS Transform Accelerates VMware Migration and Modernisation

For years, VMware has underpinned enterprise IT. But shifting licensing terms, rising costs and vendor uncertainty are prompting CIOs, CFOs and CISOs to rethink that dependency. The challenge is that migrating VMware workloads has traditionally been slow, risky and expensive. Tangled dependencies, undocumented environments and scarce institutional knowledge all conspire to stall progress. AWS Transform changes that equation, using agentic AI to help organisations retire legacy platforms and move to the cloud with far greater speed and confidence.

What AWS Transform actually does

AWS Transform is a collaborative enterprise modernisation service powered by expert AI agents and our expertise in migrations & modernisations. Rather than acting as a simple assistant, it offloads the labour-intensive work of discovery, planning and execution to specialised agents built on two decades of migration experience. It spans mainframe, Windows and VMware workloads, as well as custom code transformations.

The strategic appeal for leadership is straightforward: reduce licensing overhead, cut technical debt, and free skilled engineers to focus on innovation rather than repetitive migration tasks. AWS reports modernisation up to 5x faster, with the ability to transform hundreds of applications in parallel.

Retiring legacy software, systematically

Legacy estates rarely fail because of a single application. They fail because nobody fully understands how the pieces connect. Noventiq’s Migration and Modernization approach combined with AWS Transform addresses this directly by automatically analysing environments, building dependency graphs, extracting embedded business logic into plain language, and generating technical documentation teams can query through a chat interface. For mainframe workloads, we can refactor COBOL, DB2 and VSAM systems into modern Java Spring Boot applications. Compressing years of discovery into hours of evidence-based decisions.

The result is a de-risked path off ageing platforms, with institutional knowledge captured rather than lost as legacy specialists retire.

VMware migration, phase by phase

For VMware specifically, we structured this journey into four clear phases:

• Inventory discovery: mapping the environment automatically via AWS Application Discovery Service, or by importing existing RVTools exports.

• Wave planning: generating dependency-aware migration waves so related workloads move together, minimising disruption.

• Network conversion: translating existing network and NSX configurations into native AWS constructs such as Amazon VPC.

• Server migration: orchestrating cutover to Amazon EC2 via AWS Application Migration Service, with right-sized instance recommendations.

Throughout, human-in-the-loop approval gates keep your and our architects and administrators firmly in control. A shared web workspace keeps all stakeholders aligned. A genuine advantage for governance-conscious CISOs who need auditable, controlled change.

Why this matters to the business

For the CFO, the case is financial: eliminating costly licences and shortening multi-year projects into months of predictable effort. For the CIO, it is about agility. A modern, cloud-native foundation that keeps pace as AI accelerates the rate of change. For the CISO, it is control and visibility: documented environments, remediated end-of-life dependencies, and consistent, repeatable processes replacing error-prone manual work.

Crucially, AWS Transform combined with Noventiq's expertise reframes modernisation as an ongoing discipline rather than a one-off event. Our new continuous modernisation capability keeps codebases current and secure long after the initial migration completes.

A pragmatic next step

VMware migration no longer needs to be the daunting, multi-year programme it once was. With agentic AI handling the heavy lifting and your teams retaining oversight at every gate, legacy modernisation becomes measurable, controlled and achievable.
