Common Challenges of SharePoint Migration for Large Businesses and Enterprises

SharePoint migrations are rarely as simple as moving files from one system to another. For large businesses and enterprises, the process often involves untangling years of content sprawl, outdated workflows, and complex permissions structures. Understanding the most common SharePoint migration challenges can help organizations plan ahead, reduce risk, and ensure a smoother transition to modern platforms like SharePoint Online.

The Complexity of Enterprise SharePoint Environments

Large organizations often underestimate the complexity of their existing SharePoint environments. Over the years, systems grow organically as departments create sites, build custom workflows, and store documents without consistent governance standards. When it’s time for a SharePoint migration, this accumulated complexity can quickly become a major obstacle.

Enterprise environments frequently include:

• Thousands of SharePoint sites across departments
• Decades of accumulated files and documents
• Custom workflows and applications built over time

Each of these factors increases the difficulty of migrating to modern platforms. A typical SharePoint online migration must account for not only moving data but also rethinking how information is structured, secured, and accessed across the organization.

Without proper planning, organizations may discover that their existing content structure, permissions, and integrations are far more complicated than expected.

Common Challenges of SharePoint Migration

Migrating enterprise content requires more than copying files from one location to another. Organizations must address several technical and operational challenges during a SharePoint migration to avoid disruption and data loss.

Legacy Content Overload

One of the most common obstacles in a SharePoint migration is the sheer volume of outdated or redundant content. Over time, organizations accumulate thousands or even millions of files that may no longer be relevant.

Migrating unnecessary files increases storage costs, slows down the migration process, and makes it harder for employees to locate important documents after the transition. Many enterprises discover that a large percentage of their content can be archived, consolidated, or deleted before the migration even begins.

A thorough content audit is often required to determine which information should be preserved and which can be safely removed. i3solutions assessment engagements routinely find 20 to 40 percent more SharePoint sites during Phase 1 than the client internal inventory lists.

Poor Information Architecture

Another common challenge involves unstructured document libraries and inconsistent naming conventions. When departments create folders and document structures independently, the result is often a confusing information architecture.

During a SharePoint migration, these inconsistencies can make it difficult to map old content structures into new environments. Organizations may need to redesign their folder structures, metadata standards, and document taxonomy to support better enterprise document management in the future.

Without addressing information architecture issues, businesses risk replicating the same organizational problems in the new system.

Permissions and Security Complexity

Large SharePoint environments often contain deeply nested permission structures. Over time, users are granted access to specific folders or libraries, and those permissions are inherited by additional users or groups.

This complexity becomes a major concern during a SharePoint migration, especially when migrating to SharePoint Online. Security policies must be carefully reviewed to ensure that sensitive documents remain protected while avoiding excessive access restrictions.

In many cases, migrations reveal outdated user permissions that no longer reflect current roles or responsibilities. Addressing these issues requires careful planning and collaboration between IT teams and business stakeholders.

Customizations and Legacy Solutions

Older SharePoint environments frequently include custom web parts, scripts, and workflows built with tools like SharePoint Designer. While these solutions may have supported business operations for years, they can become difficult to migrate to newer platforms.

Many legacy customizations are incompatible with modern SharePoint online migration environments. Organizations may need to rebuild workflows using newer technologies such as Power Automate or redesign applications using modern development frameworks.

This process often requires technical expertise to ensure that critical business processes continue functioning after the migration.

Integration Dependencies

Enterprise SharePoint environments rarely operate in isolation. Many organizations integrate SharePoint with other systems, including ERP platforms, CRM tools, and financial applications.

During a SharePoint migration, these integrations must be carefully reviewed to ensure compatibility with the new environment. If integration points are overlooked, critical workflows or data connections may break after the migration.

This is particularly important in organizations that rely on SharePoint as part of their broader enterprise document management ecosystem.

Data Migration Performance Issues

Large datasets can significantly impact migration timelines. Enterprises often manage terabytes of data across multiple SharePoint environments, and transferring that information to new systems requires careful performance planning.

Network bandwidth limitations, migration tool constraints, and system performance factors can all affect how quickly data is transferred. Without proper scheduling and migration strategies, businesses may experience delays that disrupt normal operations.

Planning phased migrations and prioritizing high-value content can help reduce the impact of these performance challenges.

User Adoption and Change Management Challenges

Even when the technical aspects of a SharePoint migration are executed successfully, organizations can still face difficulties if users are not prepared for the transition.

Large businesses often experience challenges related to:

• Lack of user training
• Resistance to new interfaces
• Changes in established workflows

Employees who are accustomed to existing processes may struggle to adapt to new systems, particularly if the migration introduces changes to how documents are stored or accessed.

Successful migrations include clear communication strategies, training programs, and support resources to help users adjust to the new environment.

Organizations that invest in change management often see significantly higher adoption rates after a SharePoint online migration.

Governance Challenges During Migration

Many enterprises discover governance weaknesses during a SharePoint migration. Over time, organizations may have allowed departments to create sites, manage permissions, and store documents without consistent policies.

When migrating to modern platforms, these gaps in SharePoint governance become more visible.

Common governance challenges include:

• Lack of defined site ownership policies
• Missing content lifecycle rules
• Inconsistent permission standards

Without addressing these governance issues, organizations risk repeating the same structural problems in the new environment. A migration project provides an opportunity to establish stronger governance frameworks that improve security, compliance, and long-term system management.

When the content lifecycle rules an enterprise relies on already live in a Documentum retention schedule, with legal holds still in force, the records manager has a separate sequence to plan for moving Documentum records into SharePoint.

Why Planning and Assessment Are Critical

Successful SharePoint migration initiatives rarely happen without careful planning. Enterprises that approach migration strategically are far more likely to avoid costly mistakes and operational disruptions. Effective migration planning typically includes several key components.

Content Audits

Before migrating content, organizations should evaluate what data actually needs to move. A content audit helps identify outdated files, redundant documents, and unnecessary content that can be archived or deleted.

Governance Strategy

Developing a clear SharePoint governance framework ensures that new environments are structured, secure, and maintainable. Governance policies define how sites are created, who owns content, and how documents are managed over time.

Architecture Redesign

A migration project often provides an opportunity to rethink the entire SharePoint architecture. Rather than replicating outdated structures, organizations can redesign their environment to better support modern collaboration and enterprise document management.

Migration Roadmap

Finally, organizations benefit from developing a structured migration roadmap. This plan outlines migration phases, identifies key stakeholders, and defines timelines for moving different workloads.

A well-designed roadmap ensures the SharePoint migration process remains organized and aligned with business priorities.
