Free 1-hour migration assessment

Leave costly defaults behind.

Validus helps organisations replace vendor lock-in with open systems they can inspect, run, and keep under their own control.

Independence over lock-in Phased migration Rollback paths Clear ownership Private AI options Open infrastructure

Your technology.
Your control.

Every dependency has a cost. Keep the ones that earn it.

Cut recurring costs

Replace license fees and vendor premiums with predictable infrastructure spend.

Keep exits open

Keep your data, roadmap, and migration options under your control.

Move in phases

Run hybrid during transition. Replace only what makes sense.

Own the stack

Use systems you can inspect, change, and support.

Reduce dependence

Build systems for your business, not a vendor roadmap.

Open source migration across your entire stack.

We usually begin where lock-in is most expensive: infrastructure, data, identity, or AI operations.

Infra

Infrastructure & cloud exits

Move workloads off public-cloud or licensing-heavy platforms without forcing a one-weekend cutover.

  • Move off: AWS, Azure, GCP, VMware
  • Into: Proxmox, Kubernetes, private cloud
  • Guardrails: phased rollout, rollback paths, continuity first
Data

Database modernisation

Replace licensed database stacks with open systems that keep the data model stable while costs drop.

  • Move off: Oracle, SQL Server, licensed analytics stacks
  • Into: PostgreSQL, MariaDB, ClickHouse, OpenSearch
  • Approach: sync, validate, then cut over with fallback intact
Identity

Identity, collaboration, and control

Reduce seat-cost dependency and bring identity, file control, and internal tooling back under your own policies.

  • Move off: Microsoft 365, Azure AD, Okta, SaaS sprawl
  • Into: Nextcloud, Keycloak, FreeIPA, self-hosted collaboration
  • Outcome: data ownership, lower seat cost, cleaner access control
AI

Private AI without API dependence

Keep sensitive data close, contain API spend, and build internal AI capacity that survives vendor pricing changes.

  • Move off: OpenAI-only or Anthropic-only dependence
  • Into: self-hosted inference, private RAG, local model ops
  • Reason: keep data in-house and stop runaway API spend

You don't have to migrate everything at once.

We specialise in gradual transitions — one service at a time, with parallel systems and rollback capability throughout.

Phase one

Start where failure is survivable.

We begin on systems where the rollback path is easy and the learning value is high.

  • Start with non-critical systems
  • Validate performance
  • Build team expertise
  • Maintain rollback capability
Parallel run

Operate both worlds until the new one proves itself.

Critical services stay stable while data, auth, and workloads move in controlled stages.

  • Data synchronisation
  • Unified authentication
  • Shared infrastructure
  • Gradual workload shifting
Decision rule

Replace what earns replacement.

The target is lower risk and lower spend, not ideological purity.

  • Cost-benefit per service
  • Prioritise high-cost systems
  • Strategic vendor relationships
  • Pragmatic approach
Fallback

Cut over only when rollback is rehearsed.

Parallel systems reduce disruption and keep business continuity intact while confidence builds.

  • Low-disruption transitions
  • Comprehensive testing
  • Quick rollback procedures
  • Business continuity first

Strategic, phased migration
with minimal disruption.

Five steps, one goal: less risk.

1

Assessment & Discovery

We audit your current technology stack, identify dependencies, calculate total cost of ownership, and map migration opportunities.

  • Complete infrastructure inventory
  • Dependency mapping
  • Cost analysis & ROI projection
  • Risk assessment
2

Strategy & Planning

Design a phased migration roadmap with clear milestones, fallback plans, and cohabitation strategies.

  • Technology selection
  • Migration sequencing
  • Cohabitation architecture
  • Timeline & resource planning
3

Proof of Concept

Build working prototypes, validate approaches, and demonstrate capabilities before full commitment.

  • Pilot implementations
  • Performance testing
  • Integration validation
  • Team training
4

Migration & Cohabitation

Execute phased migration with parallel systems, ensuring business continuity throughout the transition.

  • Incremental deployment
  • Data migration & synchronisation
  • Hybrid operation
  • Rollback capabilities
5

Optimisation & Handoff

Fine-tune performance, establish operations processes, and transfer knowledge to your team.

  • Performance optimisation
  • Documentation & runbooks
  • Team enablement
  • Ongoing support planning

Why teams make the move.

Not because “open source is nice,” but because pricing pressure, control risk, and vendor dependence eventually become operational problems.

Lower spend

Reduce recurring licensing and platform costs where open alternatives make operational sense.

More control

Keep stronger ownership over architecture, exit options, and future procurement decisions.

Auditability

Use platforms your team can inspect, document, and support without waiting on opaque roadmaps.

Operational leverage

Turn “we can’t move because everything depends on it” into a staged migration plan.

Real impact

"A staged move away from proprietary cloud services reduced recurring infrastructure spend and gave the team direct control over data, deployment, and future changes."
