Environmental assessment and readiness planning
We assess the existing email infrastructure, mailbox volumes, dependencies, and compliance needs to provide a migration strategy that is consistent with Microsoft 365 and cloud ready criteria.
Migration strategy and architecture design
A migration plan is prepared based on the target platform, which can be Microsoft 365, hybrid Azure, or AWS-backed infrastructure, and it includes sequencing, coexistence, and cutover planning.
Security and compliance configuration
Prior to migration, access restrictions, data residency requirements, and security policies are defined using Microsoft 365, Azure Active Directory, and cloud security best practices.
Automatic mailbox migration execution
Mailboxes, metadata, calendars, contacts, and shared resources are all moved utilizing controlled, automated workflows to assure accuracy and consistency at scale.
Validation and user acceptance testing
After migration, validation is undertaken to ensure data completeness, folder integrity, and access rights, followed by controlled user acceptance tests.
Cutover, optimization, and ongoing support
The final cutover is completed with little disruption, followed by optimization and post-migration support for Microsoft 365, Azure, and AWS environments.

A business email migration service covers the secure transfer of mailboxes, emails, folders, metadata, calendars, contacts, shared mailboxes, and distribution lists from legacy or third-party email platforms to cloud environments such as Microsoft 365 or Google Workspace. The service also includes planning, execution, validation, and post-migration support to ensure continuity and data integrity.
Data integrity is maintained through encrypted data transfer, controlled migration workflows, and validation checks at each stage of migration. Folder hierarchy, timestamps, permissions, and mailbox structure are verified post-migration to ensure that data is complete and accurately reflected in Microsoft 365.
Yes. Email migrations are typically executed using phased or hybrid approaches that allow on-premises and cloud systems to coexist. This enables users to continue normal operations while data is migrated in the background, with final cutover planned to minimize service disruption.
DEV IT supports hybrid email environments where on-premises systems operate alongside Microsoft 365, as well as cloud architecture leveraging Azure and AWS. This flexibility allows organizations to adopt phased migration strategies while maintaining operational stability.
Security and compliance are addressed through role-based access control, policy enforcement using Microsoft 365 and Azure Active Directory, and data residency options supported by Azure and AWS regional infrastructure. This ensures alignment with regulatory, audit, and industry-specific compliance requirements.
