SharePoint Migration Services

SharePoint migration is the process of moving content, file shares, on-premises SharePoint, Google Workspace, Box, Dropbox, or older SharePoint versions, into SharePoint Online, while preserving the metadata, permissions, and version history that make that content usable. It is far more than copying files. A real migration reorganizes content into a modern structure, maps security correctly, and brings users along so the new environment is an upgrade rather than a disruption.

Migrations are where many SharePoint projects succeed or fail. Done carelessly, they lose metadata, break permissions, carry over years of clutter, and frustrate users who can no longer find their files. Done well, they are an opportunity to clean up information architecture, tighten security, and set the foundation for collaboration, governance, and tools like Viva and Copilot. The difference is planning, the right tooling, and disciplined validation. ARC has migrated large, complex environments with zero data loss and minimal disruption, and brings that same rigor to every migration.

A complete SharePoint migration addresses content, security, and people:

• Source coverage. On-premises SharePoint, network file shares, Google Workspace, Box, Dropbox, and older SharePoint versions, all into SharePoint Online.
• Metadata and version history. Preservation of metadata, document properties, and version history so nothing of value is lost.
• Permission mapping. Accurate translation of source permissions into SharePoint Online security, without over-sharing.
• Content audit and cleanup. Identifying and archiving stale or duplicate content so you migrate what matters, not the clutter.
• Information architecture. Restructuring sites, libraries, and metadata into a modern, navigable design.
• Validation and cutover. Phased cutover with post-migration validation so users land on a complete, correct environment.

Common use cases include retiring on-premises SharePoint, consolidating file shares, leaving Google Workspace or Box for Microsoft 365, and modernizing legacy SharePoint into a clean SharePoint Online structure.

ARC delivers SharePoint migration as a planned, low-risk program:

Assessment and planning. We inventory your sources, sizing, permissions, customizations, and workflows, and build a detailed migration plan with timeline and risks identified up front.

Content audit and cleanup. We help identify stale, duplicate, and obsolete content so the migration is an opportunity to declutter, not just relocate.

Architecture and mapping. We design the target information architecture and map content, metadata, and permissions to it precisely.

Pilot and migration. We pilot with a representative set, validate, then migrate in phases using proven tooling, preserving metadata, versions, and security throughout.

Validation. We run post-migration validation to confirm content, permissions, and history transferred correctly before cutover is final.

Adoption and support. We train users on the new structure and provide post-migration support so the transition sticks.

Smooth migrations are the product of preparation. ARC builds these practices in:

• Audit before you move. Clean up and archive first so you do not carry years of clutter into the new environment.
• Preserve what matters. Protect metadata, version history, and permissions, the things users notice immediately if lost.
• Redesign, don't just lift-and-shift. Use the migration to modernize information architecture and tighten security.
• Pilot first. Validate with a representative subset before the full move to surface issues early.
• Phase the cutover. Migrate in waves to limit risk and keep the business running.
• Validate and communicate. Confirm results and keep users informed so adoption is smooth.
