For global organizations undergoing an Office 365 Tenant to Tenant Migration, selecting appropriate migration windows can be challenging. Time zones, operational hours, and user availability must be factored into the scheduling strategy.

When implementing Office 365 Manual Mailbox Migration, downtime must be minimized. Staggering migrations by region and assigning localized support resources can reduce disruption. Ensure that cutovers align with non-critical periods for business units.

The same considerations apply to Tenant to Tenant OneDrive Migration. Syncing large volumes of data across regions may impact bandwidth and user access. Careful scheduling and pre-migration file backups help avoid unexpected issues.
