Replace fragile, outdated software with a modern cloud platform. Fixed price, delivered in weeks, zero data loss. We have done it before, with a named client, a public case study, and verifiable results.
Legacy systems rarely fail all at once. They fail slowly, in ways that are easy to ignore until they aren't. If any of these sound familiar, your system has likely passed the point where patching is the right answer.
We work with systems built on technology that is no longer supported, maintained, or practical to scale. Here are the most common starting points.
The most common legacy stack we replace. Classic ASP applications running on Windows IIS, often backed by Microsoft Access or early SQL Server.
.mdb and .accdb files used as production databases. No concurrent access, no remote connection, single point of failure.
Windows desktop applications built in VB6. No longer supported by Microsoft. Migrated to web-based cloud platforms.
Legacy CFML applications that are expensive to licence, difficult to host, and hard to find developer support for.
Old PHP applications without frameworks, type safety, or modern security standards. Often tightly coupled with no separation of concerns.
Spreadsheet-based operations that have outgrown their original purpose. Replaced with purpose-built internal tools with proper databases.
A structured approach that keeps the business running throughout, validates data integrity at every step, and hands over a system you fully own.
We map the existing system end-to-end: every data table, every workflow, every integration point. You get a written risk assessment and a clear picture of what the new platform needs to do.
Cloud-native architecture designed from scratch. Database schema, API structure, portal design, and user roles all agreed before any code is written. Fixed-price quote at this stage.
The new system is built while the old one stays live. Weekly demos on a staging environment. You see real, working software every week, not a big reveal at the end.
Data is exported, transformed, and loaded into the new database. Multiple validation passes compare record counts and spot-check integrity. We do not proceed until counts match perfectly.
Zero-downtime transition planned for a low-traffic window. Full source code, documentation, and training at handover. You own everything from day one.
The Drill Guys · Healthcare · Dental · Gold Coast, QLD
Complete replacement of Hermes, a 16-year-old Classic ASP application backed by Microsoft Access. Over a million rows migrated from a physical office server to a modern cloud platform with three purpose-built portals, and zero data loss.
React + TypeScript frontend, managed PostgreSQL database, global CDN, 99.9%+ uptime SLA.
Every record from the legacy system moved to the new database with zero data loss, fully validated.
Separate interfaces for staff, clients, and management, each scoped precisely to what that user group needs.
Granular permissions enforced at the database level, not just in application code.
Daily automated backups, point-in-time recovery, and managed infrastructure. No more manual backup routines.
All source code, database schemas, and IP handed over at completion. No licensing fees, no lock-in.
Fixed-price engagements. Quoted upfront after the technical audit. No hourly billing, no scope creep.
System Audit
$2,500–$5,000
1–2 weeks
A standalone technical audit of your existing system, not just a sales call. You get a written report covering system risks, data dependencies, migration complexity, and a clear recommendation.
Core Modernisation
$25,000–$60,000
6–10 weeks
A full replacement of the legacy system with a modern cloud platform: one primary portal, full data migration, and all core business logic rebuilt.
Full Platform
$60,000–$120,000+
10–16 weeks
Multi-portal platforms with complex data migrations, integrations, and advanced workflows. Suitable for systems with multiple user types, high data volumes, or significant new capability requirements.
All prices in AUD. Final price depends on system complexity, data volume, and portal requirements. Book a free technical audit for a fixed-price quote.
No offshore relay. You speak directly with the engineer building your system, every conversation, every decision.
No hourly billing surprises. The scope is locked before work starts and the price does not change unless you add to the scope.
AI-assisted development compresses timelines without cutting corners. Most projects that take traditional agencies 6–12 months are delivered in 6–12 weeks.
We have migrated over a million rows from a 16-year-old legacy system without losing a single record. Data integrity is non-negotiable.
100% of the source code, database schemas, and IP are yours at handover. No vendor lock-in. No ongoing licensing fees.
Not a theoretical capability: a live project with a named client, real metrics, and a public case study you can read in full.
Most projects are delivered in 6–12 weeks. Simple Classic ASP replacements with a single portal typically take 6–8 weeks. Multi-portal platforms with large data migrations run 10–16 weeks. We quote a fixed timeline before any work begins.
Typically between $25,000 and $120,000+ AUD, depending on system complexity, data volume, and the number of portals required. A free technical audit produces a fixed-price quote within a few days.
Yes. The new system is built and tested while the old one stays live. Data is migrated with multiple validation passes; we do not cut over until record counts match and spot checks pass.
Yes, this is our primary speciality. We have replaced a 16-year-old Classic ASP + Microsoft Access system for an Australian business, migrating over a million rows with zero data loss.
No. The new system is built in parallel. The cutover is planned for a low-traffic window and typically takes less than an hour.
You do, 100%. All code, database schemas, and IP are yours at handover. No licensing fees, no lock-in, no ongoing dependency on Bocati.
If the answer to “what happens if it goes down?” is “the business stops”, it's time to fix that. Start with a free technical audit. We'll map the system, assess the risks, and give you a clear picture of what a replacement would involve.
