We run reconciliation reports on file counts, metadata, permissions, and version history on every migration batch. We don't close a wave until everything matches — no exceptions.
SharePoint Migration Services Built Around What Actually Breaks
SharePoint Server 2016 and 2019 reached end of extended support on July 14, 2026. Microsoft has stopped issuing security patches, stopped fixing bugs, and stopped taking support calls for both versions — while affected environments keep running exactly as before, just with nobody watching for what breaks. For most compliance frameworks, that's no longer a disclosed risk. It's an active finding.
Most SharePoint migrations don't fail on migration day. They fail quietly, weeks later — a permission that never got remapped, a workflow that stopped triggering, a custom form nobody remembered depended on SharePoint Designer. Our SharePoint migration services surface all three before your migration day, not after.
We start with a fixed-scope discovery workshop, not an open-ended consulting engagement. Two to four days, on-site or remote, and you leave with a wave plan and a fixed-fee proposal — not a longer meeting booked to sell you another meeting.

Proven Migration Methodology
SharePoint Migration Services We Offer
Kellton's expertise as a Microsoft Solutions Partner means we don't run a generic checklist against your environment. Every engagement starts with a fixed-scope discovery workshop scoped to your actual content, permissions, and custom solutions — delivered in 2–4 days, with deliverables in your hands within 5 business days of close.
Farm & Tenant Inventory
A complete audit of sites, site collections, content types, managed metadata, workflows, and custom solutions across your on-premises or source environment — so scope is defined by what's actually there, not what the org chart assumes is there.
Permissions & Access Audit
We map unique permissions, broken inheritance, orphaned accounts, and group memberships. This is where most migrations quietly go wrong, so we surface the permissions debt before it becomes a production incident, not after go-live.
Custom Solutions Triage
Every InfoPath form, SharePoint Designer workflow, Nintex process, custom web part, and third-party integration gets identified and scored for remediation or rebuild — mapped to a modern equivalent like Power Apps, Power Automate, or SPFx before migration day.
Governance Readiness
We assess sensitivity labeling, retention policies, DLP configuration, and eDiscovery posture against the Microsoft Purview baseline, so the environment you land in is one your compliance team can actually sign off on.
AI-Ready, Power Platform Modernization
We don't just relocate your classic environment — we modernize what runs on top of it. InfoPath forms and SharePoint Designer workflows become Power Apps and Power Automate flows, and your environment lands governed and ready for Copilot and AI-powered search from day one.

Why Choose Kellton's Expertise for SharePoint Migration Services?
Choosing a SharePoint migration partner takes more than a tool license. At Kellton, we connect Microsoft platform depth with governance-first delivery. We don't just move your files — we deliver a target-state architecture your team can actually govern, with every custom solution mapped to a modern replacement before cutover, and a rollback plan validated before any wave goes live
Zero Data
Fixed Timeline
Every phase has a named delivery lead and a written exit criterion both sides sign off on. Slippage triggers an executive call, not a quietly rescheduled date.
Rollback on Every Cutover
A tested rollback plan is confirmed before any wave goes live. If reconciliation isn't clean, we restore. We don't improvise.
Near-Zero Downtime
Waves cut over site by site, not all at once. Your team keeps working in the current environment until each wave is validated and ready, so migration day doesn't mean a dark intranet.

Frequently Asked Questions (FAQ)
What happens to our custom code during migration?
Every InfoPath form, workflow, and custom web part is triaged during the Assess phase and mapped to a modern equivalent — Power Apps, Power Automate, or SPFx — before migration day, not discovered after.
Do we have to move fully to the cloud?
No. SharePoint Server Subscription Edition is a fully supported on-premises target if regulatory or infrastructure constraints keep you there. Target selection is confirmed during Assess, not before we've looked at your environment.
What if something doesn't reconcile after a migration wave?
We roll back. A tested rollback plan is validated before every cutover, not written after something goes wrong.
How is this different from buying a migration tool ourselves?
Tools move files. This engagement maps your permissions debt, your custom code, and your governance gaps first, so the tool executes an actual plan instead of guessing at a folder structure.
