Migrating to a modern intranet is one of the more rewarding projects an organization can undertake. A well-built SharePoint Online intranet replaces scattered files, disconnected tools, and outdated information with a single, organized hub your team actually uses. Getting there takes planning. Here are the six steps that make the difference between a migration that sticks and one that gets abandoned.
Step 1: Audit Your Existing Content
Before moving anything, understand what you have. Go through your current intranet or file storage and categorize content into three buckets: keep, archive, and delete. Most organizations discover that a significant portion of their existing content is outdated, duplicated, or no longer relevant. Moving less means a cleaner result on the other side.
Document what content exists, who owns it, and how frequently it gets used. This audit shapes every subsequent decision.
Step 2: Define Your Information Architecture
Information architecture is the structure your content lives in. A modern intranet needs a deliberate hierarchy: what are the top-level sections, how do they relate to each other, and how will users navigate between them?
Common top-level sections include departments or teams, company-wide resources, policies and procedures, and news or announcements. The goal is to organize content the way your users think, not the way your internal teams are structured. Test your proposed architecture with actual users before you build anything.
Step 3: Design Your Site Structure in SharePoint
Once you know your architecture, map it to SharePoint Online's structure. Hub sites connect related team sites and communication sites under a shared navigation and theme. Each major section of your intranet typically becomes its own site, with the hub tying everything together.
Decide on naming conventions, URL patterns, and permission models before you start creating sites. These decisions are much harder to change after content is in place.
Step 4: Build and Configure Your Sites
With structure decided, build the sites. Configure global navigation so users can move between sites without friction. Apply consistent branding including colors, logos, and fonts across all sites in the hub. Set up permissions at the site level rather than the file level wherever possible. This reduces administrative overhead and makes access management more transparent.
Build page templates for common content types so editors across the organization produce consistent results without needing design skills.
Step 5: Migrate and Organize Your Content
Move content from your audit's "keep" list into the new structure. Use the SharePoint Migration Tool for bulk migrations from file shares or older SharePoint environments. For smaller volumes, manual migration gives you the opportunity to clean up and reorganize as you go.
Assign content owners for each section and hold them accountable for keeping their areas current. Content without an owner goes stale quickly.
Step 6: Launch, Train, and Iterate
A phased launch works better than a single go-live date for most organizations. Start with a pilot group, gather feedback, make adjustments, then roll out to the full organization. Training should focus on how to find information and how to contribute content, not on technical platform features.
Plan for ongoing governance. Assign someone responsibility for the intranet's health, establish a review cycle for content, and create a clear process for requesting new sections or pages. An intranet that gets maintained stays useful. One that gets forgotten becomes the problem you were trying to solve.
