LEGACY MODERNIZATION FACTORY

AI-powered modernization: lower risk, less downtime

Our factory-based service model uses AI-assisted delivery to move entire portfolios of legacy applications, workflows, and data onto Appian—in parallel, in weeks per workflow.

Our factory model is governed, repeatable, and scalable

Appian delivers portfolio-scale modernization through the Legacy Modernization Factory—an AI-assisted, factory-based delivery model. By combining AI-assisted extraction, reusable architecture patterns, validation gates, and parallel execution, Appian turns legacy estates of applications, workflows, and data dependencies into modern operations without the risk of open-ended, project-by-project rewrites.

Portfolio modernization starts with Appian

Reduce Risk

Validation gates, governance standards, and architecture decisions established before scale — not reinvented for every project.

Accelerate Delivery

AI-assisted extraction, reusable patterns, and shared components enable production-quality workflows in 3–6 weeks.

Build Repeatability

A factory operating model equips your team for continuous modernization beyond the initial engagement.

The old way isn't built for portfolio scale

OLD WAY

•  Each application or workflow is a separate implementation

•  Architecture, governance, and tooling are reinvented per project

•  Sequential delivery limits throughput across the portfolio

•  Data migration is handled as a monolithic, high-risk side effort

•  Static roadmaps stall after the first few projects

WITH APPIAN LEGACY MODERNIZATION FACTORY

•  Rationalize the portfolio into repeatable patterns 

•  Establish architecture, governance, and validation gates once—reuse everywhere

•  Execute multiple workflow workstreams in parallel

•  Modernize data progressively: Abstract → Modernize → Decommission

•  Retire legacy systems as modernized workflows go live

How the factory works

An entry point for every level of readiness

PHASE 0

Portfolio Analysis

AI-assisted extraction and rationalization of the legacy estate into a prioritized, risk-scored backlog. 

4–12 weeks 

PHASE 1 · CORE

Foundations & Factory Blueprint

Governance, validation gates, target architecture, and shared components proven through 1–3 reference workflows.

8–16 weeks 

PHASE 2

Factory Execution

Scaled, parallel workflow delivery using the blueprint, patterns, and pipeline from Phase 1. 

3–6 weeks per workflow

THROUGHOUT

Data Modernization

Abstraction, modernization, and decommissioning of legacy data dependencies as workflows go live. 

Runs through all phases
