Senior PowerBuilder engineering notes
Technical writing for the engineers and architects working with long-running PowerBuilder applications. Upgrades, modernization, database compatibility, integrations, and the decisions that show up at IT steering committees.
Is PowerBuilder Dead in 2026? An Honest Answer
No — PowerBuilder is not dead. It is actively developed by Appeon, with PowerBuilder 2025 released in May 2025 on a regular cadence. The honest risk is not vendor abandonment but a shrinking talent pool. What that means for a business running a PowerBuilder application, and what to actually do about it.
ReferencePowerBuilder Versions and Support Lifecycle: Release Dates and End-of-Life
A reference table of every PowerBuilder release from 9 (2003) to 2025, who supports it, and how Appeon's end-of-life policy works — 24 months of standard support for non-LTS versions, 60 months for LTS. What version you are on, whether it is still supported, and when that changes.
UpgradePowerBuilder 9 to 2025: A Pragmatic Upgrade Guide
Honest, technical upgrade guide for moving a long-running PowerBuilder application from Sybase-era versions (9, 10.5, 11.5, 12.6) to current Appeon PowerBuilder 2025. Three upgrade paths, what actually breaks, and what to do in the next six months.
MigrationSybase to Appeon PowerBuilder Migration: 9 Things That Will Surprise You
What actually changes when you move from Sybase-era PowerBuilder (up to 12.6) to Appeon PowerBuilder (2017–2025). Nine specific surprises we hit in real migrations, with practical workarounds.
DatabasePowerBuilder + Oracle 19c: Compatibility, Gotchas and Migration
What breaks, what just works, and what to test first when upgrading the Oracle database under a long-running PowerBuilder application from 11g/12c to 19c (and onward to 23ai). Character sets, drivers, PL/SQL changes and execution-plan surprises.
IntegrationPowerBuilder REST API: 4 Integration Patterns That Actually Work
Four production-tested patterns for PowerBuilder applications talking to REST APIs: native HTTPClient (Appeon era), WinHTTP fallback (legacy PB), sidecar microservice, and gateway-in-front. With auth handling, retries and trade-offs.
DecisionModernize PowerBuilder or Rewrite in .NET? A Decision Framework
A sober decision framework for the rewrite-versus-modernize question on a long-running PowerBuilder application. Why most rewrites fail, why most modernizations succeed, and the specific situations where rewriting is the right call.
