A successful SharePoint 2016 migration requires organizations to assess content, permissions, workflows, applications, integrations, dependencies, and business requirements before migration. SharePoint migration services can provide the expertise and execution support needed to move complex workloads to SharePoint Online, SharePoint Server Subscription Edition, or another appropriate destination while creating a cleaner, more manageable environment.
With SharePoint Server 2016 now out of support, many organizations are planning their migration or modernization efforts for 2026 and beyond. However, before planning the move, organizations should understand what end of support means for their existing environment and take a structured approach to manage complexity, reduce disruption, and protect critical business operations throughout the migration.
In this blog, we outline the key steps for planning a successful SharePoint Server 2016 migration, from preparing and piloting content to migrating in waves, minimizing disruption, and validating the results.
SharePoint Migration Services: Where Should You Start?
The starting point of a SharePoint migration can significantly influence the outcome of the entire project. Without a clear understanding of the existing environment, teams can overlook dependencies, underestimate complexity, or encounter issues after migration has already begun. A well-defined migration plan creates a shared understanding among IT teams, business owners, and users, helping keep the migration aligned with business requirements and reducing avoidable disruption.
Use this SharePoint migration checklist to cover the key planning activities before migration:
- Define the Migration Scope: Establish which sites, libraries, lists, applications, and workloads the project will move. A clear scope prevents unexpected content from entering the migration plan.
- Assign Business Ownership: Give each workload a business owner who can confirm requirements, validate migrated content, and approve the completed migration.
- Map Dependencies: Document connections between SharePoint, applications, authentication, integrations, and other Microsoft services. These dependencies can affect migration sequencing and testing.
- Set Acceptance Criteria: Define what each workload must pass before the team considers the migration complete. Include data accuracy, permissions, functionality, and user validation.
SharePoint Data Migration Steps
SharePoint data migration becomes more predictable when organizations prepare content before moving. A structured approach can reduce complexity and disruption.
These SharePoint migration best practices can help organizations prepare content, test the migration approach, and move workloads in controlled waves:
- Prepare: Start by assessing the content and dependencies in your SharePoint Server 2016 environment. Inventory sites, libraries, lists, metadata, versions, permissions, workflows, applications, and integrations, then determine how each will be migrated, modernized, consolidated, archived, or retired in the target environment.
- Pilot: Test your migration approach with a representative workload before moving large volumes of content. Include different content types, permission models, metadata, applications, workflows, and integrations, and have users complete real business tasks. Use the results to identify issues, refine your migration process, and confirm that content, access, functionality, and the target environment’s search experience work as expected.
- Migrate: Move content in manageable waves based on business units, workload complexity, dependencies, criticality, or readiness. For each wave, confirm the scope and ownership, migrate the planned content, validate the results, communicate changes to users, and resolve issues before moving to the next wave. This phased approach gives teams greater control and helps limit business disruption.
How to Minimize Business Disruption During SharePoint Migration
Business continuity should remain central throughout the migration. Employees should not discover after migration that a critical document, application, workflow, or business process has changed unexpectedly.
- Identify time-sensitive and business-critical workloads early and prioritize them based on their operational impact and dependencies.
- Schedule migrations around business operations to minimize downtime and avoid disrupting critical activities. Communicate planned changes well in advance.
- Prepare employees for the transition by explaining where they will find content, how access may change, which links or processes may be affected, and where to report issues.
- Involve representative users in pilot testing and validation for critical workloads to identify usability and business-process issues that technical testing may miss.
- Establish validation, contingency, and rollback procedures, where technically feasible, for high-impact workloads so teams can respond quickly if the migration does not meet business or technical requirements.
How to Validate and Stabilize Your SharePoint Migration
Technical migration reports can identify failed items and other errors, but technical completion does not necessarily mean the migration has succeeded. Business users must confirm that the new environment supports their work.
Validation should cover:
- Data: Confirm that required content, metadata, and versions migrated accurately.
- Access: Verify that users have the appropriate permissions and restricted information remains protected.
- Functionality: Test applications, forms, workflows, and integrations.
- Search: Confirm that users can find migrated information through the expected search experience.
- Business operations: Have users complete representative tasks and confirm that critical processes work as expected.
Post-migration, allow time for stabilization. Monitor user issues, resolve exceptions, review access problems, and address unexpected behavior. Focus on improving information architecture, simplifying permissions, strengthening governance, optimizing search, and enhancing collaboration or automation.
Building a SharePoint Migration Strategy for Business Continuity
A successful SharePoint migration strategy requires coordinated planning across data, technology, users, and business processes. Organizations can reduce disruption by assessing their environment, preparing content, mapping dependencies, testing representative workloads, migrating in controlled waves, and validating each workload before moving forward.
The transition can also create a stronger foundation for Microsoft 365 and AI initiatives by improving information architecture, content quality, permissions, governance, and discoverability. Instead of simply reproducing the SharePoint Server 2016 structure, organizations can improve information organization, simplify access, retire unnecessary content, and create a better employee experience.
