Migrating data between Office 365 tenants involves several critical steps. The first step is assessing the source and target tenants to understand the data volume, dependencies, and potential challenges. This is followed by planning the migration, including creating timelines, prioritizing data, and identifying tools for the task.

The migration process typically includes pilot testing, actual data transfer, and post-migration validation. Testing ensures the process works smoothly, while post-migration checks confirm that all data has been successfully transferred and that users can access their tools without issues. A clear roadmap for these steps ensures a seamless migration experience.
