Deadline-driven migration campaign

SharePoint 2016/2019 End-of-Support Migration

SharePoint Server 2016 and 2019 environments are approaching the point where delay becomes operational risk. We help teams inventory farms, identify modernization blockers, and move content, workflows, and collaboration patterns into SharePoint Online and Microsoft 365.

What this solves

  • Assess farms, site collections, content databases, permissions, workflows, forms, customizations, and integrations.
  • Design the SharePoint Online, Teams, OneDrive, retention, search, and ownership model before migration waves begin.
  • Run pilots, phased cutovers, validation checkpoints, owner communications, and post-migration hypercare.

Why this matters

Migration risk usually hides in ownership, permissions, identity, workflows, integrations, and business validation. Our role is to surface those risks early, design the Microsoft target state, and guide the move with clear controls.

Know what must move

Separate active business content from stale sites, abandoned libraries, unsupported customizations, and archives.

Reduce cutover risk

Map authentication, custom code, InfoPath, Nintex, SharePoint Designer workflows, reports, and line-of-business integrations.

Land in a cleaner model

Use the migration to simplify information architecture, permissions, ownership, sharing, retention, and Teams-connected collaboration.

Proof of fit

Representative scenarios we support

Buyers need to see that you understand their exact migration environment. These examples make the service tangible without relying on unverifiable metrics.

Tenant, SharePoint, Teams, OneDrive, Exchange, and Power Platform moves with real business validation requirements.
Migration programs where permissions, ownership, workflows, forms, integrations, or compliance constraints create risk.
Organizations that need senior Microsoft migration judgment, not only tool operation.

Before

What creates drag

  • Unclear scope, unknown owners, hidden dependencies, and migration waves based on incomplete inventory.
  • Technical migration success measured mostly by item counts, while business validation is left until late.
  • Legacy patterns copied into Microsoft 365 without improving governance, support, or ownership.

After

What good looks like

  • An inventory-backed plan with owners, dependencies, target architecture, validation gates, and remediation priorities.
  • Migration waves aligned to business processes, support readiness, communications, and go/no-go decisions.
  • A cleaner Microsoft operating model with governance, documentation, and post-migration support paths.

How we approach it

Each engagement is adapted to your tenant, source systems, timeline, risk tolerance, and internal team capacity.

Inventory and risk scan

Collect site, library, storage, permission, workflow, form, customization, and usage signals.

Target design

Define SharePoint Online architecture, hub structure, Teams mapping, labels, sharing controls, and owners.

Remediation sprint

Fix orphaned owners, broken inheritance, unsupported templates, workflows, metadata, and oversharing.

Pilot and cutover

Run pilot migrations, validate outcomes, refine mappings, and execute production waves.

Typical deliverables

You get practical artifacts your administrators, project managers, and business owners can use immediately.

FAQs

Is this only for SharePoint Server 2019?

No. We can assess and plan migrations from SharePoint Server 2013, 2016, 2019, Subscription Edition, and hybrid environments.

Can you handle legacy forms and workflows?

Yes. We identify InfoPath, Nintex, SharePoint Designer, custom scripts, timer jobs, and integration dependencies, then recommend retire, rebuild, replace, or migrate paths.

Do we need to migrate everything?

Usually no. A strong plan distinguishes content to migrate, archive, remediate, modernize, or retire.
