1. Discover
Collect source facts across users, sites, files, mailboxes, forms, workflows, permissions, integrations, ownership, and business processes.
Delivery methodology
A migration methodology built for messy Microsoft environments
Real migration work is not a copy operation. It is a controlled business transition across content, identity, ownership, permissions, forms, workflows, governance, and support.
The Horton Scientific migration framework
Each phase produces artifacts that reduce risk and help business owners, technical owners, and executives make decisions.
2. Inventory
Turn discovery into structured data: source-to-target maps, dependency registers, owner lists, volume reports, and workload scopes.
3. Rationalize
Decide what to migrate, modernize, archive, retire, consolidate, or defer before copying complexity into Microsoft 365.
4. Design
Define target architecture for Microsoft 365, SharePoint Online, Teams, OneDrive, Exchange Online, Power Platform, Azure, security, and governance.
5. Migrate
Execute pilot and production waves with tooling, automation, validation, communications, go/no-go checkpoints, and rollback considerations.
6. Validate
Test business outcomes, not only item counts: access, approvals, forms, workflows, search, links, reporting, owners, and support paths.
7. Govern
Stabilize the target state with ownership, environments, DLP, retention, external sharing, monitoring, admin runbooks, and change control.
8. Support
Provide hypercare, issue triage, post-migration cleanup, managed services, and ongoing optimization after go-live.
Product accelerator
Move legacy forms with Form Migrator
For organizations with InfoPath or legacy form sprawl, Form Migrator gives the modernization effort a product-led path instead of a one-form-at-a-time rebuild cycle.
Where Form Migrator fits
- ✓Inventory and rationalize forms before rebuilding them in Microsoft-native patterns.
- ✓Prioritize high-value forms by business criticality, usage, data complexity, and owner readiness.
- ✓Support a repeatable migration motion across Power Apps, Power Automate, SharePoint, Dataverse, and governance workstreams.
Product accelerator
Move Nintex workflows with Flow Migrator
For teams moving Nintex and legacy workflow estates into Power Automate, Flow Migrator helps turn discovery, mapping, and rebuild planning into a repeatable migration motion.
Where Flow Migrator fits
- ✓Identify workflow candidates, dependencies, owners, triggers, approvals, and failure points.
- ✓Separate direct rebuilds from processes that need redesign, governance, or integration architecture.
- ✓Accelerate migration planning from Nintex into supportable Power Automate patterns.
Controls
What makes the method different
✓ Business validation is planned before migration waves begin.
✓ Forms and workflows are first-class workstreams, not late-stage exceptions.
✓ Product accelerators are used where they reduce repeatable work.
✓ Target tenant governance is designed before production cutover.
✓ Migration tools are selected after source complexity is understood.
✓ Executives receive risk and decision summaries, not only technical reports.
