Microsoft Exchange Server 2013 has served organizations reliably for over a decade. But with its end of support in April 2023, businesses are now exposed to potential security vulnerabilities, compliance risks, and increased maintenance costs.
This shift forces IT decision-makers to consider the next step: continue on-premises with a newer Exchange version or move to the cloud with Microsoft Office 365.
Regardless of the migration path—whether upgrading Exchange on-premises, moving to Office 365, or adopting a hybrid approach—every project comes with its own challenges. This is where EdbMails Exchange Migration and Office 365 Migration softwares prove invaluable. Purpose-built for reliability and simplicity, EdbMails delivers seamless, secure, and zero-downtime migrations. All mailboxes, public folders, and archives are transferred with complete fidelity, enabling organizations to modernize their email infrastructure without disrupting day-to-day operations.
Deployment Models: Choosing the Right Path with EdbMails Support
On-Premises Exchange 2013 to Newer Versions
Organizations that wish to retain full control of their email infrastructure often choose to upgrade to a newer on-premises Exchange server. Exchange 2016 and Exchange 2019 are the natural upgrade paths.
- Why upgrade? Staying on-premises ensures customization, strict compliance control, and internal data sovereignty.
- The challenge: Manual upgrades can be time-consuming and error-prone, especially when dealing with large mailboxes and legacy systems.
👉 With EdbMails Exchange Migration tool, you can directly migrate from Exchange 2013 to Exchange 2016 or Exchange 2019 without double hops or manual exports. The tool preserves folder hierarchy, permissions, calendars, contacts, and public folders.

Microsoft Office 365 (Cloud Deployment)
Office 365 offers a modern, cloud-first approach. Businesses no longer need to invest in servers or worry about hardware failures. Instead, they pay a predictable per-user subscription, gaining access to Exchange Online along with Teams, SharePoint, OneDrive, and Office applications.
- Why migrate? Office 365 improves scalability, remote work accessibility, and collaboration, while eliminating heavy IT overhead.
- The challenge: Large-scale migrations from Exchange 2013 can be risky without the right tools. Downtime, lost attachments, or broken folder structures can disrupt business operations.
👉 EdbMails Exchange Migration tool simplifies the process with:
- Cutover, staged, and hybrid migration support
- Incremental sync (no duplicate items)
- Zero downtime migration
Hybrid Deployment
A hybrid deployment combines on-premises Exchange 2013 with Office 365. Many large enterprises use this model to migrate gradually, maintain regulatory compliance, or test workloads before committing fully to the cloud.
EdbMails supports hybrid Exchange 2013 to Office 365 migrations, ensuring smooth coexistence and staged mailbox transfers. This allows IT teams to migrate executive mailboxes, shared mailboxes, or specific departments first before moving the entire organization.
Office 365 Tenant to Tenant Migration
Mergers, acquisitions, or restructuring often create a need to migrate between different Office 365 tenants. These migrations are among the most complex, as they involve mailboxes, OneDrive, Teams, and SharePoint data.
- The challenge: Native tools require multiple steps and manual intervention, leading to downtime and user disruption.
- The solution: EdbMails Office 365 Tenant-to-Tenant Migration tool simplifies this process by:
- Supporting direct tenant-to-tenant transfers without intermediate hops
- Maintaining permissions, folder hierarchy, shared mailboxes, and groups
- Offering incremental migration to avoid duplicates and save bandwidth
- Ensuring zero downtime so end users can continue working uninterrupted
