Legacy Backporting

Modern connectivity — with support for legacy systems that can’t change overnight.

Not every business can replace legacy platforms on day one. Older ERPs, warehouse systems and bespoke applications often power mission-critical processes, even when they don’t support modern formats or APIs.

Legacy Backporting helps you keep those systems running while still benefiting from modern integrations and trading partner requirements.

The problem it solves

Legacy systems don’t fail because they’re “bad” — they fail because the world around them changes:

• retailers update requirements and validations

• new partners require different formats or faster onboarding

• older systems can’t output the structure partners expect

• upgrades are risky, expensive, or operationally impossible short-term

• teams end up running manual workarounds to keep trading

Legacy Backporting bridges modern requirements to older platforms safely.

What Legacy Backporting does

Maintain compatibility with older formats

Support older document structures and integration patterns where modern alternatives aren’t available.

Translate modern flows into legacy-friendly outputs

Convert newer data structures into outputs your legacy systems can consume, without forcing immediate replacement.

Reduce operational disruption during upgrades

Keep trading live while you modernise at your own pace, rather than pausing operations for a “big bang” migration.

Protect audit trails and traceability

Even when legacy outputs are used, the flow remains traceable end-to-end within the platform.

How it works

1) Identify the legacy constraint
For example: fixed file layouts, older message versions, or limited integration methods.

2) Apply transformation and routing rules
XEDI maps modern document flows into the structure your legacy system expects.

3) Keep flows stable
Documents continue moving while your legacy system remains unchanged.

4) Upgrade when ready
As systems are replaced or modernised, you can shift to newer flows without rebuilding everything from scratch.

Key benefits

• Keep trading without disruption: legacy doesn’t block progress

• Lower migration risk: modernise safely, step by step

• Reduce manual workarounds: fewer “temporary” processes that become permanent

• Faster partner onboarding: meet modern partner requirements while staying compatible internally

• Long-term flexibility: move to modern systems on your timeline

Best-fit use cases

• Older ERP or WMS platforms with limited export options

• Businesses mid-migration who need a stable bridge

• Multi-site operations where system change is complex

• Organisations with bespoke legacy applications

• Teams under pressure to meet updated retailer requirements quickly

FAQ

Does Legacy Backporting mean we can avoid upgrading forever?
It helps you keep trading reliably while you modernise. Most teams use it to reduce risk and avoid rushed system changes.

What kinds of legacy systems can this support?
Any system with stable inputs/outputs can usually be supported, whether that’s older file layouts, message versions, or limited connectivity methods.

Will this affect traceability?
No — even when legacy-compatible outputs are used, documents remain traceable with status and event history.

Can we move off legacy backporting later?
Yes — the goal is to give you flexibility. As systems are upgraded, flows can shift to modern formats without a full rebuild.
