Strangler fig pattern
Route traffic feature-by-feature to new services while legacy keeps running.
Qbatch · App Modernization
Migrate legacy systems without stopping the business.
Strangler patterns, cloud migration, and UI refreshes that cut tech debt while keeping revenue flowing. We modernize incrementally — not big-bang rewrites.
Modernization path
STEP 1
Audit
Architecture, debt, and risk map
STEP 2
Strategize
Strangler vs replatform vs refactor
STEP 3
Extract
Slice services off the monolith
STEP 4
Migrate
Data, traffic, and cutover plans
STEP 5
Retire
Decommission safely
Capabilities
Modernize live — not on a parallel universe.
Users keep working while you replace the engine underneath.
Monolith decomposition
Identify bounded contexts and extract services without a freeze.
UI modernization
Refresh frontends on modern stacks while backends transition.
Zero-downtime cutovers
Blue/green deploys, feature flags, and rollback plans for every migration step.
Data migration
Dual-write, backfill, and validation so nothing gets lost in transit.
Cost & perf wins
Cloud-native targets that reduce run costs and improve reliability.
Before
- Monolith deployments that take hours
- Frameworks past end-of-life
- Features blocked by tangled dependencies
After
- Audit — Architecture, debt, and risk map
- Strategize — Strangler vs replatform vs refactor
- Extract — Slice services off the monolith

App Modernization FAQ
Rewrite or refactor?+
We default to incremental modernization unless the codebase is truly unmaintainable. Audits determine the right mix.
Can you work alongside our team?+
Yes — we often pair with internal engineers, document patterns, and leave them owning the new architecture.
How long does modernization take?+
Depends on system size. Most engagements show first migrated services in 8–12 weeks with a multi-quarter roadmap for full retirement.
