A lot of SharePoint projects start with the same goal: get our content into Microsoft 365. That is a migration. It is necessary, but on its own it often moves the same problems to a new address.
Modernization asks a different question: now that we are moving, what should this look like? The organizations that get the most value out of Microsoft 365 treat the move as both.
What Migration Actually Means
Migration is the technical move of sites, libraries, lists, and permissions from one environment to another. Done well, it is careful, tested, and low on disruption. But a pure migration, often called lift and shift, keeps everything as it was:
Same structure: deep subsite hierarchies and folders nested six levels down.
Same permissions: years of one-off access grants that nobody fully understands.
Same clutter: outdated files, abandoned sites, and duplicate content.
Same workarounds: custom code and legacy workflows that may not run in SharePoint Online at all.
The result works, technically. Users just log into a newer platform and find the same frustrations they had before.
What Modernization Adds
Modernization uses the migration window to rethink how SharePoint supports the business. It typically touches three areas:
The User Experience
Modern SharePoint looks and behaves very differently from classic sites. Communication sites, team sites connected to Microsoft Teams, and hub sites make content easier to find and easier to publish. Pages work on mobile. Navigation can reflect how people actually work instead of how the org chart looked in 2014.
Security and Governance
A move is the best chance you will get to clean up permissions. Modernization means rebuilding access around Microsoft 365 groups, applying sensitivity labels and retention policies through Microsoft Purview, and setting clear rules for who can create sites and share externally. It also matters for AI: Microsoft 365 Copilot surfaces whatever a user has access to, so messy permissions become a real exposure risk.
Information Architecture
Microsoft recommends a flat structure of independent sites connected through hubs, rather than layers of subsites. Flattening your architecture during the move makes it easier to reorganize later, apply consistent governance, and scale as teams change. Metadata and content types can replace folder sprawl so search actually works.
Why the Difference Matters
Migrating first and modernizing later sounds efficient. In practice, “later” rarely comes, and when it does, you are restructuring content that was just moved and retraining users who just adjusted. Doing the work once saves time and budget.
There is also a cost to standing still. Many organizations are moving off SharePoint Server 2016 and 2019 now that those versions have reached end of support. If you are already committed to a migration, the incremental effort to modernize is far smaller than running a second project down the road.
Building a SharePoint Modernization Strategy
Modernization does not mean redesigning everything. A practical strategy focuses on what matters most:
This is what modern workplace transformation looks like in practice: not a big reveal, but a series of deliberate decisions that make the platform easier to use and easier to manage.
Make Your Move Count
If you are planning a SharePoint migration, it is worth asking what you want the platform to look like on the other side. Compass365 helps organizations migrate and modernize in one project, so the result is a workspace people actually want to use.
