My Sites in SharePoint Server (on-premises)

My Sites in SharePoint Server (2013, 2016, 2019) provide a personal site for each user. Each site includes:

• Personal document library: private file storage accessible only to the user.
• Shared document library: files the user shares with colleagues.
• About Me page: user profile with skills, interests, and org chart position.
• Newsfeed: social activity stream (replaced by Yammer/Viva Engage in later versions).
• Followed content: sites, documents, and people the user follows.

My Sites in SharePoint Online (Microsoft 365)

In Microsoft 365, the My Site architecture has three components. Each replaced part of the on-premises My Site.

• OneDrive for Business: replaces the personal and shared document libraries. 1 TB per user by default.
• Microsoft 365 profile: replaces the About Me page. Integrates with Delve, LinkedIn, and Viva Insights.
• Viva Engage / Yammer: replaces the Newsfeed for org-wide social collaboration.

My Site migration considerations

When migrating from SharePoint on-premises to SharePoint Online, My Site content must be handled separately from team sites.

• Personal document libraries → OneDrive for Business (user-by-user migration).
• User profile data → Microsoft 365 profile (synced from Azure AD and HR systems).
• Followed content → re-established in SharePoint Online after migration.
• Permissions on shared My Site documents must be validated post-migration.
• SharePoint Admin Center controls My Site host URL and storage quotas.

OneDrive governance

EPC Group configures OneDrive governance policies to protect user data and meet compliance requirements.

• Storage quotas by user group or license tier.
• External sharing policies — restrict sharing to verified domains.
• Sensitivity labels via Microsoft Purview — auto-classify files by content type.
• Retention policies — configure default retention for OneDrive content.
• Data lifecycle management — archive OneDrive of departing employees.

Frequently asked questions

What happened to My Sites in SharePoint Online?

My Sites have been replaced by OneDrive for Business for personal file storage and the Microsoft 365 user profile, which includes About Me, skills, and org chart. The Delve experience highlights profile information. Additionally, Viva Engage has taken the place of the social newsfeed.

How do I migrate My Site content to OneDrive?

To migrate your My Site document library to OneDrive, you can use the SharePoint Migration Tool (SPMT) or Microsoft FastTrack.

Remember that permissions must be remapped manually. Also, user profile data syncs separately through Azure AD.

EPC Group specializes in enterprise-scale My Site migrations, ensuring zero data loss.

Can users access their old My Site after migrating to Microsoft 365?

No. Once the on-premises SharePoint environment is decommissioned, the My Site URL will go offline. Content must be migrated to OneDrive before the cutover.

EPC Group validates the content migration and notifies users of their new OneDrive URL. This is part of every engagement.

How much OneDrive storage does each user get?

Microsoft 365 Business and Enterprise plans provide 1 TB of OneDrive storage for each user by default. Admins can adjust individual user quotas, but these cannot exceed the tenant limit.

For Microsoft 365 E3 and E5 plans:

• Unlimited archiving is available for Exchange.
• OneDrive quotas are managed separately.
