Modernize Smarter: Replace Legacy Apps with ServiceNow + DTech Apps — Not Power Apps

Keep your content in Microsoft 365. Run your workflows in ServiceNow. Transform legacy forms and siloed systems into governed, AI-powered workflows—without hidden costs or chaos.

Enterprise Governance

App Engine Studio, Flow Designer, PAD, and AEMC deliver low-code speed with centralized control. ATF ensures testable, repeatable releases.

Files Stay in SharePoint

DocIntegrator keeps all documents in SharePoint—permissions, versions, metadata—while ServiceNow orchestrates tasks, SLAs, and approvals.

AI that Knows Workflows

Now Assist accelerates build and run with AI that understands ServiceNow tables and flows—beyond form-centric generation.

Why App Engine + DocIntegrator Outperforms Microsoft-Only Approaches

  • Enterprise-grade workflow & governance
    ServiceNow App Engine is purpose-built for complex, cross-department processes with AEMC guardrails and ATF. Power Apps builds fast—but often leads to environment sprawl, API throttling, and Dataverse cost creep.
  • Keep every file in SharePoint—no duplicates
    DocIntegrator provides deep SharePoint operations—view, edit, sign—without duplicating attachments. Microsoft 365 remains the content system of record; ServiceNow governs the workflow.
  • One system of action, connected to enterprise data
    Requests, tasks, SLAs, and audits live in ServiceNow with native dashboards and analytics—no fragile stitching required.
  • AI that is workflow-aware
    Now Assist accelerates development and operations with context-aware automation for routing and approvals.
  • Total cost & risk over the portfolio
    App Engine standardizes governance, testing, and release management across apps—lowering long-term risk compared to a sprawl of Power Apps.

“All documents stay in SharePoint. All workflows stay in ServiceNow.”

  • FedRAMP/DoD-ready platform controls
  • Unified SLAs & audit trails
  • Lower storage costs via SharePoint offload

How It Works: Reference Architecture

Microsoft Teams ↔ SharePoint Online ↔ DocIntegrator ↔ ServiceNow App Engine

Flow Designer • AEMC • ATF • Now Assist

System of Action

ServiceNow App Engine for workflows, SLAs, automation, AI, and auditability.

Content System of Record

SharePoint via DocIntegrator for secure storage, permissions, metadata, and versions.

Collaboration Surface

Teams for notifications, chat, and approvals connected to ServiceNow.

CapabilityApp Engine + DocIntegratorMicrosoft Power Apps
Document handlingFiles remain in SharePoint; permissions, versions, metadata preserved; seamless access from ServiceNow.Connectors provide access; deeper cohesion often requires custom build and premium tiers.
Workflow depthPlatform-native flows, SLAs, tasks, approvals; portfolio-level governance.Fast UI; cross-app orchestration usually needs Dataverse + custom governance.
Governance & SDLCAEMC + multi-instance pipelines + ATF regression testing.Managed Environments improving, but often reactive to app sprawl.
AI assistanceNow Assist grounded in ServiceNow data and workflows.Copilot is form-centric; workflow cohesion varies by app design.
Total cost of ownershipUnified controls lower long-term cost and risk across portfolio.Premium tiers & API limits increase cost as apps scale.

Best-Fit Modernization Scenarios

Document-Heavy Processes

Permits, contracts, investigations, project documentation, quality records.

Cross-Department Workflows

HR ↔ IT ↔ Legal ↔ Finance orchestration with unified SLAs and dashboards.

Regulated & Audited Environments

Government, defense, healthcare, financial services—full traceability and control.

A Pragmatic Decision Rule

Choose App Engine + DocIntegrator if the app is…
  • Document-centric and cross-department
  • Audit/SLA-driven and likely to scale
  • One of many legacy replacements
Consider a Power App if the app is…
  • Small, team-specific, and stays within M365
  • Light workflow needs (budget for Premium if it grows

90-Day Modernization Blueprint

  1. Portfolio Triage: classify by document intensity, scope, audit needs.
  2. Platform Setup: deploy AES, AEMC, ATF; define Dev/Test/Prod guardrails.
  3. Content Integration: connect SharePoint via DocIntegrator; enforce single source of truth.
  4. Collaboration: enable Teams notifications and approvals.
  5. Pilot Two Apps: one document-heavy, one approval-centric; add Now Assist.
  6. Scale: publish ATF suites, SDLC pipeline, and citizen-dev standards.

Executive Takeaway

For serious legacy modernization: ServiceNow App Engine + DTech Apps DocIntegrator deliver enterprise governance, AI-assisted workflows, seamless Teams/SharePoint integration, and a lower total cost of ownership—creating a sustainable factory for replacing legacy apps.
