OneDrive Tenant-to-Tenant Migration: 2-Wk Consulting Service

IT Partner LLC

OneDrive file migration from one tenant to another, with minimal downtime for employees.

Usually, you will need this type of migration when a company merges or acquires another company, or you would like to migrate to a different geographic region.

This service enhances Microsoft 365 efficiency by seamlessly migrating data between tenants. It ensures uninterrupted access to files and documents, minimizing downtime. With pre-stage and final data transfers, users can swiftly resume tasks. Overall, it streamlines transitions, maintaining productivity.

The process of data transmission is implemented in two stages - first, we do the pre-stage migration and transfer all the files from one tenant to another; depending on the amount of data, it can take quite a long time. Employees can continue to work with their files from any device without noticing the transfer process.

At the second stage, employees will need to temporarily stop working with files at a predetermined time. At this point, we will implement the final transfer of data that has been changed since the first migration; this is a much smaller amount of information, and its transfer takes a short time, which results in a small period of non-working time for employees.

We use our own software for the data migration. This allows you to avoid data loss and errors during the transfer process.
