De-risk legacy replacement with faster, governed delivery.
Legacy modernization fails when it asks the business to wait too long for value. We use OutSystems to wrap or replace priority workflows incrementally so teams see business movement before the full estate is modernized.
Legacy Monolith Modernization
Legacy modernization on OutSystems focuses on wrapping or replacing aging business systems with modern web and mobile workflows while core records remain protected during transition. The priority is continuity, adoption, and risk-managed change rather than a risky big-bang rewrite.
Fit signals.
- Your legacy business app requires expensive desktop licensing or VPNs
- Making a single database field change takes months of change requests
- Your legacy system is running on out-of-support platforms or is difficult to change safely
- You need custom workflow features that your legacy ERP does not support
What we deliver in Legacy Modernization.
Every capability below is practiced across multiple production engagements — not a scoping checklist.
Incremental replacement
- Co-existence planning while legacy systems remain live
- Legacy data mapping and synchronization
- Workflow-by-workflow migration sequencing
Enterprise integrations
- Legacy system and partner connectivity
- Custom integration support where the platform needs extension
- Identity and single sign-on mapping
The shapes this work
usually takes.
Legacy wrapper launch
A focused engagement to deliver a modern mobile or web workflow over a legacy system, unlocking a blocked operational use case.
Incremental system replacement
Phased modernization of a complex legacy application, delivering functional areas in controlled releases.
Pitfalls we've seen
and how we avoid them.
Recreating the legacy system pixel-for-pixel
The biggest pitfall is replicating outdated legacy workflows in OutSystems. We focus on business outcomes, not recreating legacy UI patterns.
Ignoring governance patterns
OutSystems makes it easy to build quickly, which can create future complexity. We define boundaries, ownership, and release rules up front.
Common questions about Legacy Modernization.
We use secure connectivity patterns approved by your infrastructure and security teams, then expose only the data and actions needed for the new workflow.
