Key developer dependency
One internal expert holds the knowledge of a system that pays salaries. When they retire or change roles, the company is exposed.

Where long-running PowerBuilder systems build up risk
Long-running PowerBuilder applications are valuable and deeply embedded. They tend to share a small set of operational realities that benefit from senior, focused attention.
Unsupported PowerBuilder versions
Older runtimes still in production. No clear upgrade plan, growing distance from current Appeon releases.
Database and server upgrades
Oracle, SQL Server, OS or virtualization upgrades approach — and nobody can confirm the application will survive them cleanly.
Missing documentation
Critical business logic lives only in .pbl files and people's heads. Onboarding new engineers takes months.
PowerBuilder support, modernization and integrations
Six ways to work with us, covering the realities of mature enterprise PowerBuilder applications — production support, careful modernization and the senior expertise you can't realistically recruit in a quarter.
PowerBuilder Support
Senior production support, troubleshooting, small fixes, stabilization and continuity for PowerBuilder applications that are running but no longer easy to maintain in-house.

PowerBuilder Modernization
Upgrade planning, PowerBuilder 2022 / 2025 readiness, UI improvements, deployment modernization, PowerServer / PowerClient strategy.
scoped · phased · safe
PowerBuilder Integrations
SAP, REST APIs, reporting systems, PDF/document workflows, external platforms — bridging PowerBuilder cleanly into the wider enterprise stack.

PowerBuilder modernization without business disruption
Modernize safely. Don't rewrite blindly.
Not every PowerBuilder application needs a rewrite — and for most, a rewrite is the riskiest option on the table. We assess what you have, cut the operational risk, and move forward in safe, reversible steps that protect the business in production.
01
Assess
We map your codebase, architecture, database and the business-critical workflows the system quietly runs — so every decision is made on facts, not guesses.
A clear, written risk map — before you commit to anything.
02
Stabilize
We fix the urgent risks, document the fragile areas and make the system supportable again — a calmer baseline before any structural change.
Fewer surprises, and a system your team can actually maintain.
03
Modernize
Version upgrades, deployment, APIs and integrations — delivered in small, reversible phases, each one tested before it reaches your users.
Current, supported and cloud-ready — with no big-bang cutover.
04
Evolve
We stay on as a senior partner, supporting the system while it moves, step by step, toward an architecture you can keep building on.
A system you can plan around for years — not one you fear.

PowerBuilder expertise, with the rest of the stack in view
PowerBuilder is the core specialization, but enterprise legacy systems rarely live in isolation. We work across databases, integrations, reporting, deployment environments and the business processes the application actually supports.
That breadth is what makes the difference between a fix and a fix that survives the next upgrade.
PowerBuilder / Appeon ecosystem experience. Independent specialist practice. We work with the platform every working day and stay current with each release.

Three ways to work with us
Engagement shapes sized to real situations. No retainers larger than they need to be — and no full-team minimums for systems that just need a senior pair of hands.
Ad hoc consulting
Occasional analysis, troubleshooting or advisory work. Hours per engagement, no monthly commitment.
- Targeted investigation & diagnosis
- Architecture & code reviews
- Second-opinion advisory
- Hourly or fixed-scope
Monthly Support Retainer
Guaranteed access to PowerBuilder expertise — incidents, small changes, advisory and knowledge transfer, every month.
- Reserved capacity & response time
- Production incident support
- Small changes & maintenance
- Quarterly health review
Modernization assessment
A fixed-scope review of the application, its risks, an upgrade path and the practical options for the next 24 months.
- Codebase & architecture review
- Risk & dependency report
- Upgrade & modernization roadmap
- Executive-ready summary
Typical situations we help with
Real-world scenarios where conservative enterprise teams call us in. If your situation looks like one of these, we can help.
Is your last PowerBuilder expert leaving?
Knowledge concentrated in one or two people who are nearing retirement or moving on. The risk needs to be addressed before the calendar forces it.
Does the system work, but nobody wants to touch it?
A long-running PowerBuilder application that everyone is reluctant to change. Small changes feel risky, large changes feel impossible.
Is a database, server or OS upgrade ahead?
Oracle, SQL Server, Windows Server or virtualization changes are coming — and the application needs to survive them cleanly.
Need SAP, API or reporting integration?
A PowerBuilder application that needs to talk to SAP, REST services, modern reporting or document/PDF workflows.
Considering modernization without a risky rewrite?
Evaluating PowerBuilder 2022 / 2025, PowerServer or PowerClient — and weighing modernization against a full rewrite the business cannot afford.
Stuck with undocumented legacy business logic?
Critical logic that exists only in .pbl files and people's memories — and needs to be made legible to the rest of the organization.

Talk to a PowerBuilder engineer
Support for a stable legacy system, a risky upgrade, or a modernization path that won't disrupt the business. Send a short description — your version, database, integrations and the situation you're in — and we'll come back with a practical next step. No long forms, no obligation.
You'll usually hear back within one business day — from an engineer who works in PowerBuilder, not a sales desk.
