Lessons Learned from Large-Scale Migrations

Large-scale content migrations are more than moving files—they’re complex projects requiring careful planning, the right tools, and lessons from experience. Here are five key takeaways:

Plan Before You Move

Successful migrations start with thorough planning. A few extra weeks upfront can save months of fixes later.

• Inventory your content: Identify critical files and determine what can be archived.

• What is the target system? SharePoint Online is the most common.

• Run a pilot migration: Test a small subset of data to catch mapping errors, incompatible file type, and other issues early. SharePoint does have a few flaws, find them first.

  
  

Use the Right Tools

Manual processes or basic software rarely suffice. Dedicated migration tools, like Peregrine Migrate, handle large volumes, automate error management, and provide detailed logs, keeping the project on track.

Communicate with Users

Migration impacts people as much as systems.

• Involve business experts for mapping and validation.

• Communicate early, provide training, and offer post-migration support. User engagement drives adoption and minimizes disruption.

Validate After Migration

Moving files isn’t the finish line. Validation ensures content is correct, permissions work, and everything is in the right place. Budget time and resources for this phase—often called Hypercare—to resolve issues quickly and reassure users.

Prepare for Problems

No migration is flawless. Unexpected file types, network issues, or permissions will arise.

• Identify risks and define an error-handling process before starting.

• Use tools with detailed error reporting to fix problems fast and reduce stress.

Conclusion

Successful migrations hinge on planning, proper tools, and user focus. Challenges are inevitable, but clear processes and preparation make the journey smooth and efficient.
