Why SharePoint Migrations Fail

Most SharePoint migrations do not fail because the copy tool cannot move files. They fail because the project underestimates ownership, permissions, workflows, information architecture, communications, and validation.

Common failure patterns

• No reliable site owner list
• Broken inheritance and direct user grants copied without review
• Legacy workflows discovered late in the project
• File shares mapped into SharePoint without redesigning information architecture
• Teams, SharePoint, and OneDrive treated as separate projects
• Business users asked to validate content without a clear checklist

What reduces risk

• Start with an assessment and risk register
• Run pilot waves with representative sites and users
• Define go/no-go criteria before cutover
• Validate business processes, not only item counts
• Plan post-migration hypercare and admin handover

The migration should leave the organization with a Microsoft environment that is easier to operate than the one it replaced.
