Switching to M365 E3?
Enterprise rollouts of M365 E3 often involve migrating thousands of mailboxes from on-premises infrastructure. If your organization is running Exchange Server 2016 or 2019, our on-premises Exchange to Office 365 migration service uses hybrid connectivity to move mail, calendars, and public folders with zero user disruption. For older Exchange 2013 environments, we handle the staged migration path that Microsoft recommends for large mailbox counts.
Consolidating multiple M365 tenants after a corporate acquisition? Cross-tenant mailbox migration is one of the most complex M365 projects. Our Microsoft 365 tenant-to-tenant migration team has handled mergers involving 5,000+ mailboxes — including Teams channels, SharePoint document libraries, OneDrive data, and Entra ID identity mapping.
Organizations making the switch from Google Workspace at the enterprise level face additional complexity around shared drives, Google Vault data, and Google Groups. Moving from Gmail to Outlook and Google Drive to OneDrive requires careful planning around permissions, retention policies, and user retraining. We run a parallel-operations period so teams can access both platforms during the transition. For a broader view of what is involved, see our complete Microsoft 365 migration services overview.
