39knots — Data migration to Microsoft 365

We know the water

Twenty five years in enterprise IT and hands-on SharePoint experience going back to its earliest releases mean we've already seen the failure modes — broken permissions, orphaned metadata, half-synced libraries — before they happen to you.

You keep the ship

You stay in command of the timeline, the risk decisions and the final sign-off. We plan the route, run the crossing and hand you documented, governed data on the other side — nothing surprises your IT team during process and afterward.

precision Every file, permission and metadata field accounted for before it moves.
continuity Your team keeps working during the migration, not around it.
governance A permission model that still makes sense a years later.
transparency You see the plan, the risk log and the status — not just the invoice.
craft Twenty years of experience, not a script and pray migration during weekend.

What we move, and how

Every engagement starts with an inventory of what's actually on the source side — not an assumption about what should be there.

Professional Audit

We audit and deliver report of your infrastructure to find existing SharePoint servers, File servers, complexity of data, retired or deprecated legacy features, custom solutions, all bottlenecks, potential risks.

Network Share → Teams / SharePoint Online / OneDrive

Personal and departmental file shares restructured into governed cloud storage, with ownership, permissions and security logic that reflect how the business actually works.

SharePoint On-Premises → SharePoint Online

Full-fidelity migration of sites, libraries, lists, permissions and metadata — including the customizations that make a straight lift-and-shift risky.

Tenant to Tenant migration

Full-fidelity migration of sites, libraries, lists, documents and metadata — including mapping of Employees from one Tenant to other.

Legacy file server decommissioning

Deduplication, archival and clean-up before the old server goes dark, so you're not paying to migrate twenty-year-old orphaned data.

Microsoft Teams provisioning

Teams and channels structured around departments and workflows, not around whatever the file tree happened to look like in 2014.

Governance & adoption

Permission models, retention policies and short, practical training so the new structure holds up after we leave.

Artur Maroszek

Founder, 39knots

Getting hired is the easy part. Keeping a client's trust through a migration that touches every file they own — that's earned one clean crossing at a time.

Artur has spent twenty five years in enterprise IT, starting as one of the first people anywhere to work hands-on with SharePoint through a Microsoft Gold Partner. That early work grew into a specialty in Intranets, Process Automation and, eventually, Data Migration — a field he's now spent 10 years focused on working exclusively for carrying out data migrations for companies with a global reach spanning over 93 countries worldwide. Over that time, financial and manufacturing global giants have trusted him to move their most valuable data. 39knots is where that experience becomes a dedicated practice.

From the shore of your Data Center to the open water of Microsoft 365 Cloud.
