Modernisation

Existing contracts expire. New commercial frameworks open. Agencies that have their transition capability in place before the deadline move. Those that don't, wait.

Urgency Hard Deadline: Oct/Nov 2026

Existing IaaS and TaaS contracts expire October and November 2026. Agencies without transition plans in place now are already behind.

The Situation

A Hard Deadline Is Not a Strategy.

Existing all-of-government infrastructure contracts are expiring. New commercial frameworks open access through the Government Marketplace on modern, flexible terms that include cloud-native and software-defined capability. For most agencies, this is not a routine renewal. It is a transition that requires planning, architecture, and specialist execution.

Contract expiry without a transition plan

Oct/Nov 2026 is a fixed point. Agencies that haven't started scoping their transition now are compressing the window for design, procurement, and migration execution into a timeline that doesn't accommodate delay.

BAU running on ageing infrastructure

Legacy servers, on-premise environments, and end-of-life platforms create operational risk while the transition is planned. Most agencies don't have spare internal capacity to manage the BAU environment and execute the migration simultaneously.

Cloud migration is not a lift-and-shift

Modern infrastructure frameworks expect cloud-native design, software-defined networking, and security-by-design. Migrating existing workloads without rearchitecting them replicates technical debt in a new environment.

The Delivery Window

There Is Less Time Than It Looks Like.

Infrastructure transitions involving procurement, architecture, and migration have predictable timelines. Working backwards from the contract expiry reveals how little planning runway remains.

Now - Q1 2026

Transition scoping and architecture

Current-state assessment, target architecture design, and migration sequencing. This is the work that must be done before procurement can open. Agencies without capability in place now are already at risk of compressing this phase.

Q2 2026

Procurement and vendor engagement

SOW finalisation, Marketplace procurement, and specialist resource engagement. Procurement cycles take time. The agencies that start Q2 with architecture ready will finish. Those still scoping in Q2 will not.

Q3 2026

Migration execution and parallel running

Workload migration, network transition, and parallel environment management. The peak delivery phase. Specialist engineers, network architects, and cloud platform specialists required at full capacity.

Oct/Nov 2026

Contract expiry. No extension assumed.

Existing IaaS and TaaS contracts expire. Agencies on new Marketplace agreements are operating under modern commercial terms. Agencies still mid-transition are managing risk.

"The agencies that start with architecture capability in Q1 finish the migration on time. The ones that wait for the SOW to be signed first do not."
What Lexel Delivers

From Architecture Through to Managed Operations.

The full infrastructure transition lifecycle. One relationship covering every phase without a new procurement at each handover.

BUILD

Infrastructure Assessment & Architecture

Current-state infrastructure audit, cloud readiness assessment, target architecture design, and migration sequencing plan. Delivered as a scoped outcome with defined deliverables before migration begins.

BUILD

Migration Tranches

Azure cloud migration, workload rearchitecting, and platform build for defined migration tranches with bounded scope and milestones.

SCALE

Cloud & Platform Engineering

Specialist cloud engineers and platform architects deployed across the migration window.

BUILD

Network Modernisation

Software-defined networking, SD-WAN, and network uplift aligned to new TaaS framework requirements.

SCALE

Network Transition

Network architects and engineers deployed as the network transition workstream opens. Continuity from design through to commissioning.

BUILD

Backup, DR & Resilience

Backup and disaster recovery architecture and implementation for new DR capability delivery.

RUN

Ongoing DR & Monitoring

Ongoing managed backup, monitoring, and recovery testing once the environment is live.

RUN

Managed Infrastructure Operations

Post-migration managed infrastructure service. Server management, patching, performance monitoring, incident response, and capacity management. SLA-backed continuous operations from the team that executed the migration.

How the Model Fits

One Approval. Every Phase of the Transition.

BUILD

Architecture and migration, scoped and delivered.

Infrastructure assessment, target architecture, and migration tranches are defined-outcome workstreams. SOW via Government Marketplace Professional Services. Fixed deliverables, fixed accountability.

Govt Marketplace SOW
SCALE

Specialist engineers when the workstream opens.

Cloud architects, platform engineers, network specialists, and migration engineers placed via AOG TAS. Agency-directed. Available within 48 hours. Stepped down when each workstream closes. No emergency hire cycle mid-transition.

AOG TAS - 48hr deployment
RUN

Operations handed off from day one of go-live.

The team that delivered the migration transitions to managed infrastructure operations. No onboarding gap. No context rebuild. Managed service covering the new environment from the moment it goes live.

Managed Service Agreement

The engineer who built the environment manages it. No handover. No knowledge loss. No gap between delivery and operations.
