2026
Extended support for SharePoint Server 2016/2019 ends July 14, 2026 - migration is no longer optional for on-prem environments.
The clock isn't abstract anymore. It's a real deadline.

SharePoint Migration
A bad migration moves the mess along with the files. Skysecure fixes the structure before the move.
Skysecure assesses content, permissions, metadata and workflows before migration, then builds a modern SharePoint environment that is governed, searchable and easier for people to use.

The migration finishes.The platform still loses.
SharePoint migrations are rarely a simple file transfer. Years of organic growth - sites nobody governed, permissions granted one-off, folders nested ten levels deep - collide with SharePoint's actual behavioral limits, and a "completed" migration can still leave you with an unusable estate.
What it looks like from outside
A flat file share with sprawling folders, pushed into SharePoint Online without redesign
Thousands of unique, undocumented permission exceptions built up over years
Documents that lose their tags, categories, and searchability on arrival
Workflow history and approval records that quietly don't come along for the ride
What it actually is
Permission sprawl - large environments routinely develop thousands of unique permission rules nobody can account for.
Metadata breakdown - content that arrives without proper tagging becomes unfindable, defeating the purpose of the platform.
A structural mismatch - a folder hierarchy that worked as a file share can genuinely collapse SharePoint's performance if migrated as-is.
A silent data gap - approval records, run logs, and audit trails are dropped by default unless exported beforehand.
The risk isn't moving files.
It's moving them without a redesign.

What Skysecure Does For You
We don't just copy your files. We redesign the structure around them.
Anyone can run the SharePoint Migration Tool. What prevents a migrated environment from collapsing under its own sprawl is redesigning the information architecture first - permissions, metadata, and folder structure rebuilt for how SharePoint actually behaves, not copied blindly from the old file share.
SharePoint Online
The Platform
A modern intranet and document platform in Microsoft 365.
- Modern intranet and document platform built into Microsoft 365
- Flexible site structure, metadata, and permission models
- Native integration with Teams, OneDrive, and Power Platform
- Built-in migration tooling for moving from file shares or legacy sites
The Migration Team
Accountable for the redesign, not just the file copy.
- Information architecture redesigned before a single file moves
- Permissions consolidated into a clean, group-based model
- Metadata and tags carried over correctly, so content stays findable
- Governance rules built in from launch, so sprawl doesn't return
Four disciplines. One governed environment.
This is what "migrated properly" actually means in practice — not a file copy, but four disciplines working together.
1
Information Architecture
Site and library structure redesigned around user needs — not a direct copy of a decade-old folder hierarchy.
2
Permission Cleanup
Thousands of accumulated one-off permission exceptions consolidated back into a manageable, group-based model.
3
Metadata Preservation
Tags, categories, and classification carried over correctly, so content stays findable after the move.
4
Ongoing Governance
Provisioning rules and policy enforcement built in from launch, so sprawl doesn't rebuild itself within a year.
We recommend the migration and governance approach your environment's real complexity actually needs.

What our customers say about our sharepoint migration
Permission Cleanup
"We went from 4,000 unique permission entries to a governed structure our IT team can actually explain in one page."
IT Director

Findability
"Documents are findable now. That sounds basic, but it's the first time in years."
Operations Head
Engineering Firm
Oversized Files
"Skysecure caught our CAD file archive would have silently failed the standard migration tool's size limit - before it became a production problem."

Questions business owners actually ask
Should we just copy our current folder structure into SharePoint Online?
We recommend against it. A flat file share with sprawling folders that worked on-prem can genuinely collapse SharePoint's performance if migrated as-is - redesign is part of the project, not optional polish.
Will our permissions carry over exactly as they are?
What happens to our SharePoint Designer workflows?
Do we need to migrate everything at once?
Can Skysecure see the contents of our documents during migration?
How long does a typical SharePoint migration take?
Your content, finally findable.Governed from day one.
