IT Partner’s OneDrive Tenant-to-Tenant Migration service moves OneDrive files from one Microsoft 365 tenant to another, typically for mergers, acquisitions, or moves to a different geographic region. The service includes analysis, planning, pre-stage migration, final migration, user informational messages, verification, and a project closeout report. ### When should a company use this OneDrive migration service? A company should use this service when it needs to move users’ OneDrive data from one Microsoft 365 tenant to another, such as after a merger, acquisition, divestiture, or regional tenant change. The service is designed specifically for OneDrive for Business tenant-to-tenant file migration, not for workstation, mobile device, or broader endpoint configuration. ### What is included in the OneDrive Tenant-to-Tenant Migration service? The service includes a OneDrive usage analysis, a usage report and migration plan, pre-stage data migration with result evaluation, final data migration, informational messages for users, verification and issue fixing, and a project closeout report. The closeout report includes final project status, acceptance criteria matching, outstanding issues, and the final budget. ### What is not included in this OneDrive migration service? The service does not include workstation configuration, customer team training, mobile device configuration, or documentation beyond the project closeout report. More extensive documentation can be provided for an additional fee if needed. ### How long does the OneDrive tenant-to-tenant migration take? The listed service duration is 5 days, but the plan may vary depending on your needs and the amount of OneDrive data. With large volumes, the pre-stage migration can take longer, which is agreed in the migration plan. ### How is the OneDrive Tenant-to-Tenant Migration priced? The service is priced at $10 per user plus a $1,500 tenant fee, quoted in writing before work begins — you pay after you approve delivery. The tenant fee covers analysis, planning, and cutover coordination; the per-user fee covers each migrated OneDrive account. ### Will employees be able to keep working during the migration? Employees can continue working with their files during the pre-stage migration, because IT Partner transfers files while users continue working from desktop, mobile, or web access. During the final migration, employees must temporarily stop working with files at a predetermined time so IT Partner can transfer changes made since the pre-stage migration. ### Is there downtime during the OneDrive migration? Yes, there is a planned temporary work stoppage for OneDrive files during the final data migration. This downtime is scheduled in advance, because IT Partner must complete the final transfer of data changed since the initial pre-stage migration. ### What does IT Partner need before starting the migration? The prerequisite is a Microsoft 365 tenant with an appropriate OneDrive for Business license. The client must also provide administrative access to both the source and new tenants, coordinate resources and schedules, and assign a dedicated point of contact to work with IT Partner. ### What are the client’s responsibilities during the migration? The client is responsible for coordinating internal resources and staff schedules, providing a dedicated point of contact, granting administrative access to the source and new tenants, coordinating outside vendors, configuring networking equipment such as firewalls and switches, and reviewing and approving deliverables in a timely manner. These responsibilities are important because tenant access, scheduling, and network readiness affect the migration plan and execution. ### What migration tool does IT Partner use? IT Partner uses its own software for the OneDrive data migration. The service description states that this is done to avoid data loss and errors during the transfer process. ### How does IT Partner verify that the migration was successful? IT Partner verifies the migration results and fixes issues as part of the implementation plan. The success criteria are that all data is transferred to the appropriate OneDrive accounts in the new tenant according to the migration plan and that OneDrive is available for desktop and mobile devices as well as the web version. --- Fixed-price engagement by IT Partner LLC.
