Core services
Migration work built around the Microsoft ecosystem.
The technology is only one part of the move. Identity, permissions, ownership, unsupported features, testing, and cutover decisions have to work together.
SharePoint migration and modernization
Move from SharePoint Server, file shares, or another tenant while addressing structure, permissions, ownership, and customizations.
Explore SharePoint servicesPower Platform modernization
Replace InfoPath, Nintex, and SharePoint Designer solutions with supportable Power Apps and Power Automate patterns.

Assessment-led planning
Plan the move before changing the environment.
A migration assessment turns scattered technical facts into a decision-ready plan. Your team sees what can move, what needs remediation, and what must be decided before a pilot begins.
- Current-state inventory and ownership map
- Dependency, exception, and risk register
- Target architecture and decision log
- Pilot scope, migration waves, and cutover plan
Representative engagement
One migration plan across identity, mail, collaboration, and content.
Cross-workload migrations fail when each platform is treated as a separate project. Horton Scientific connects the technical dependencies, owners, pilot groups, communications, and cutover sequence in one operating plan.
Review representative workTypical work products
01
Discovery inventory
Users, workloads, sites, permissions, integrations, and ownership.
02
Dependency log
The items that affect sequencing, testing, or the target design.
03
Pilot findings
Evidence from a representative workload and the updates required before scale.
04
Cutover runbook
Roles, timing, checks, issue handling, communication, and rollback decisions.
Delivery method
A clear path from discovery to handoff.
Each stage produces decisions, evidence, and working documents. The process is visible to the project team instead of being hidden inside a migration tool.
- 01
Assess
Inventory the estate, owners, dependencies, and constraints.
- 02
Plan
Define the target, decisions, migration waves, and acceptance criteria.
- 03
Pilot
Test a representative workload and update the runbook with evidence.
- 04
Migrate
Execute the move, track issues, and validate each workload.
- 05
Stabilize
Resolve post-cutover issues and hand over usable documentation.
Purpose-built migration software
Tools developed from the work itself.
Use the products directly, or use them as part of a consulting engagement. Each product addresses a specific part of migration work that is otherwise repetitive and difficult to estimate.
Workflow modernization
Flow Migrator
Analyze Nintex exports, identify compatibility and dependencies, and prepare supported Power Automate conversions.

Planning resources
Start with the questions that shape the project.
Use the checklists and templates before a call to surface ownership, dependencies, scope, and cutover decisions early.

Tell us what you are moving.
Share the source, destination, timing, and the part causing concern. We will reply with the first technical questions, not a generic sales script.
Your request goes to the Horton Scientific team.
An NDA is available when the discussion requires it.
You can also book a consultation or buy consulting hours.
Common questions
Before you bring in a migration partner.
A useful first conversation should clarify scope, ownership, technical dependencies, and the decision that has to be made next.
What Microsoft workloads do you migrate?
Horton Scientific supports Microsoft 365, SharePoint Online, Teams, OneDrive, Exchange Online, Power Platform, Azure, and tenant-to-tenant migration scenarios. The assessment identifies which workloads and dependencies belong in the same plan.
Can we start with an assessment instead of a full project?
Yes. The migration assessment is a fixed-scope starting point that documents the source, target readiness, technical risks, open decisions, migration waves, and recommended next steps.
Do you work with internal IT teams and other migration partners?
Yes. Horton Scientific can lead the work, own a defined workstream, or provide specialist support alongside your internal team, managed service provider, or migration-tool partner.
Can we buy help for a small or urgent task?
Yes. Pay-As-You-Go blocks are available for design reviews, troubleshooting, scripts, migration planning, cutover support, and other defined Microsoft tasks.
Do you migrate InfoPath and Nintex solutions?
Yes. Horton Scientific inventories and modernizes legacy forms and workflows for Power Apps and Power Automate. Form Migrator and Flow Migrator can also reduce manual analysis and conversion work for supported patterns.
