Modernise and Migrate Legacy Systems Without Breaking What Australian Customers Rely On
MicroPyramid is a 14-year-old senior-led engineering team that helps Australian startups and SMBs migrate off ageing platforms, rescue unstable products, and modernise legacy systems into maintainable, scalable software. We work in phases — with afternoon overlap during Australian working hours, AUD billing via Stripe, and Privacy Act-aware data migration from the start.
The hardest part of any Australian migration is moving data without breaking compliance: the Privacy Act 1988, the Australian Privacy Principles, and OAIC expectations all matter the moment customer data is in motion. We migrate with AWS ap-southeast-2 (Sydney) available for Australian data residency, and we have worked directly with teams across healthtech, fintech, and resources tech on keeping live products stable through change.
Why Australian Teams Trust Us With a Migration
Four reasons Australian founders and product teams choose MicroPyramid to modernise and migrate critical systems
Migration Standups in Step With AEST
AEST runs roughly 4–5 hours ahead of IST, giving a solid afternoon overlap. During a migration that means live standups, same-day cutover decisions, and pull-request reviews plus end-of-day handoffs timed for your morning — not surprises you discover the next day.
Privacy Act & APPs-Aware Migration
Data migration is where compliance risk is highest. We move data with the Privacy Act 1988 and the Australian Privacy Principles in mind (regulator: the OAIC), and AWS ap-southeast-2 (Sydney) is available so Australian customer data stays resident in Australia throughout.
AUD Billing via Stripe
Invoices in Australian dollars, collected via Stripe, with GST-compliant invoicing available on request. No currency-conversion overhead, no wire-transfer friction — billing that fits how Australian businesses actually run a migration budget.
De-Risked, Senior-Owned Delivery
Migrations fail when they are handed to juniors and run as big-bang rewrites. Senior engineers own every cutover, phase, and rollback plan directly. The person scoping your audit is the person running your migration.
Modernisation & Migration Services for Australian Teams
Six services covering the full range of legacy challenges — from audit and framework upgrades to data and cloud migration
Legacy System Audit
A written assessment of your ageing PHP, Django, .NET, or monolithic system — architecture, dependency and support risk, security exposure, and a prioritised roadmap. Australian teams get a clear picture before committing budget to any rebuild.
- Architecture and structure review
- Dependency and end-of-life risk
- Migration options and trade-offs
Framework & Version Upgrades
Safely upgrade ageing Django, Python, or .NET systems off unsupported versions while improving maintainability, performance, and security — without breaking what Australian customers already rely on.
- Django and Python version upgrades
- Dependency cleanup and patching
- Performance bottleneck removal
Product Rescue & Recovery
When a codebase is unstable, undocumented, or inherited from a previous agency, we stabilise production first and create a safe path forward — the situation many Australian SMBs find themselves in after a contractor leaves.
- Production triage
- Technical debt mapping
- Handover recovery
Re-Platforming & Phased Migration
Design migrations that reduce risk and preserve business continuity through module-by-module replacement. No big-bang rewrites — incremental cutover that keeps Australian operations running throughout.
- Phased migration planning
- Module-by-module replacement
- Staged cutover with rollback
Data Migration & Residency
Move off ageing databases with structured, low-risk plans and integrity validation. Migrations are designed with the Privacy Act 1988 and the Australian Privacy Principles in mind, with AWS ap-southeast-2 (Sydney) available for Australian data residency.
- Oracle / MySQL to PostgreSQL
- Data integrity validation
- Australian data-residency handling
Cloud Migration to AWS Sydney
Migrate on-premise or legacy-hosted systems to AWS ap-southeast-2 (Sydney) — containerised, observable, and right-sized. Reduce operational risk while keeping Australian customer data within Australian borders.
- Lift-and-shift or re-architecture
- Containerisation with Docker
- ap-southeast-2 (Sydney) deployment
Choose the Right Path
These four paths keep the lane clear. The goal is to pick the smallest change that meaningfully improves the system for your Australian users.
Modernise
Keep the core product, upgrade risky layers, and improve maintainability when the business logic still makes sense for your Australian customers.
Use this path when: Best when the product still works for the business but the codebase is slowing delivery.
Migrate
Move off an ageing framework, vendor, database, or hosting platform in stages while protecting continuity for Australian users and operators.
Use this path when: Best when you need a safer transition plan — including cloud migration to AWS Sydney — not a dramatic rewrite.
Rescue
Stabilise an inherited or failing system first, then decide what should be cleaned up, migrated, or replaced.
Use this path when: Best when the current state is fragile, undocumented, or already causing production pain.
Rebuild
Replace the system only when the current architecture is beyond saving and the business case is genuinely clear.
Use this path when: Best when repair costs and product constraints clearly outweigh a staged replacement.
Australian Teams We Work Best With
If any of these situations match where your Australian system is right now, we should talk
Australian Products That Cannot Evolve
Your product still works, but every change is painful. Delivery is slow, technical debt is high, and nobody on your Australian team trusts the codebase enough to touch it.
SMBs on Unsupported Systems
Running on outdated Django, end-of-life .NET, or ageing PHP that creates ongoing security and compliance risk — and makes Privacy Act and APP obligations harder to meet.
Teams Inheriting Messy Codebases
A previous agency or contractor left a fragile system behind. You need stabilisation and a clear handover before your Australian team can grow the product again.
Founders Needing a Safer Path
You know the current system has to change, but a full rewrite sounds risky, expensive, and operationally dangerous for a live Australian customer base. You want a de-risked alternative.
Australian Teams Blocked From Adding AI
You want AI search, copilots, or workflow automation, but the current architecture and data model are not ready for it. Modernisation has to come first.
Businesses Facing Migration Deadlines
A hosting provider is sunsetting, a framework hit end-of-life, or a vendor contract is ending. You need a migration owned by senior engineers working in step with your Australian timezone.
Best Fit For
- Australian fintech, healthtech, govtech, and resources-tech teams stuck on ageing PHP, legacy Django, .NET, or monoliths
- SMBs whose data migration has to respect the Privacy Act 1988, the Australian Privacy Principles, and OAIC expectations
- teams that need AWS ap-southeast-2 (Sydney) data residency as part of a cloud migration
- founders who want incremental, de-risked migration with senior ownership — not a speculative rewrite
Not the Right Fit When
- greenfield product builds with no existing system to modernise or migrate
- engagements wanting a big-bang rewrite with no audit, sequencing, or rollback plan
- staff augmentation without delivery ownership of the migration itself
- teams treating AI as a slogan rather than a capability the modernised system should enable
If you are starting a fresh product rather than migrating an old one, see Product Engineering for Australian Teams.
Public proof for Australian teams: Refactored.ai shows complex re-platforming carried out without disrupting live users, and Bough Digital is an agency platform we have modernised and kept stable through change.
How an Australian Modernisation Engagement Starts
Every engagement starts with an audit — so you know exactly what you are dealing with before committing to any changes
Audit the Current System
We assess architecture, dependencies, risks, bottlenecks, and Australian compliance constraints — delivered as a written report.
Define the Right Path
Not every system needs a rewrite. We recommend the smallest viable path that meaningfully improves the situation.
Stabilise Before Big Changes
If the product is fragile, we reduce immediate risk before pushing major migrations or architectural changes.
Migrate in Phases
We prefer phased migration over big-bang rewrites — preserving business continuity and data integrity throughout.
