What is Microsoft Cloud Migration?
Microsoft Cloud migration is the process of moving your business from on-premise servers or another email platform to Microsoft 365 — with zero downtime, complete data integrity, and a modern, secure workplace that lets your team work from anywhere, on any device, from day one.
On-premise email servers and legacy systems slow your team down, create security risks, and cost more to maintain every year. eMazzanti manages every stage of the migration: tenant setup and licensing, email and mailbox migration, SharePoint and OneDrive file migration, security and compliance configuration, user provisioning, and 90 days of post-migration support — so your business never stops running during the transition.
Small teams can get started immediately with the Quick Start plan — O365-to-O365 migrations of up to 10 mailboxes, from $50/mailbox, buy online with no quote needed. Larger or more complex migrations from Exchange, Google Workspace, GroupWise, Zimbra, or Lotus Notes are scoped and managed as a full project by eMazzanti's certified migration engineers.

Microsoft Cloud FAQs
How long does it take to migrate from on-premise Exchange to Microsoft 365?
The duration of an Exchange to Microsoft 365 migration depends on the number of mailboxes, the total volume of email data, and the complexity of the existing configuration. A small organization with fewer than 50 mailboxes can typically complete a migration in one to three days with proper planning. Larger organizations with hundreds of mailboxes, complex distribution groups, and shared resources generally require one to three weeks. The most important factor is not the raw data size — it is the preparation: auditing existing accounts, cleaning up inactive mailboxes, and configuring coexistence so users can send and receive email from both environments during the transition. A well-planned migration causes zero downtime for end users.
What is the difference between a cutover migration and a staged migration to Microsoft 365?
A cutover migration moves all mailboxes from on-premise Exchange to Microsoft 365 in a single batch, typically over one weekend. It is the simplest approach and works well for organizations with fewer than 150 mailboxes that want to complete the transition quickly. A staged migration moves mailboxes in batches over weeks or months, allowing the organization to prioritize certain departments or user groups while maintaining email flow between the on-premise server and Microsoft 365 during the transition. Staged migrations reduce risk for larger organizations but require managing a hybrid coexistence environment for a longer period. A third option — hybrid migration — establishes a permanent or long-term coexistence and is typically used by enterprises that need to keep some mailboxes on-premise.
Will I lose any emails or data during a migration to Microsoft 365?
A properly executed Microsoft 365 migration should result in zero data loss. All emails, calendar items, contacts, and tasks can be migrated from the source system — whether Exchange, Google Workspace, Novell GroupWise, or a legacy POP/IMAP account. The risk of data loss comes from poor planning rather than the migration process itself: skipping a pre-migration audit, failing to account for PST files stored locally on user machines, or migrating without verifying that all data has transferred before decommissioning the source server. Best practice is to confirm migration completeness and allow users to verify their mailboxes before the source system is shut down.
What happens to shared mailboxes, distribution lists, and public folders during a Microsoft 365 migration?
Shared mailboxes, distribution lists, and public folders each require specific handling during a Microsoft 365 migration and are among the most commonly overlooked elements. Shared mailboxes can be migrated to Microsoft 365 shared mailboxes directly and do not require a paid license for read-only access by multiple users. Distribution lists need to be recreated or synchronized in the new tenant with the correct membership. Public folders — used in older Exchange environments — require a separate migration process to either Microsoft 365 public folders or SharePoint Online, depending on how the content is being used. A thorough pre-migration audit that inventories all of these objects prevents surprises on go-live day
What does eMazzanti's Microsoft 365 migration service include from start to finish?
eMazzanti manages the complete Microsoft 365 migration end to end. This includes tenant setup and configuration — creating the Microsoft 365 environment from scratch with accounts, licenses, domains, security policies, and retention settings — followed by full email and mailbox migration from any source platform. File migration to SharePoint and OneDrive is included, with full library setup and OneDrive Files On-Demand configured. eMazzanti also handles user provisioning and licensing, security and compliance configuration including Microsoft Purview settings, and delivers Masterclass training before go-live plus 90 days of post-migration support to ensure full user adoption and return on the investment.
Which source platforms can eMazzanti migrate to Microsoft 365?
eMazzanti migrates to Microsoft 365 from any source platform, including on-premise Microsoft Exchange (the most common migration), Microsoft 365 tenant-to-tenant (for mergers, acquisitions, or rebranding), Google Workspace (Gmail, Google Drive, Google Calendar), Novell GroupWise, legacy Outlook PST files and POP/IMAP accounts, and other platforms including Zimbra and Lotus Notes. The approach is tailored to the specific source system and organizational requirements — no migration is too complex, and eMazzanti has experience with all of the platforms listed.
What is the Quick Start migration option eMazzanti offers for small teams migrating between Microsoft 365 tenants?
For small organizations migrating between two Microsoft 365 tenants — a common need during mergers, acquisitions, or rebranding — eMazzanti offers a Quick Start option starting from $50 per mailbox with a $600 setup fee, purchasable online without a custom quote. This covers O365-to-O365 tenant-to-tenant migration for up to 10 mailboxes per order, including all email migrated from source to destination tenant and user accounts created on the new tenant. Migration is confirmed before work begins so there are no surprises. For larger migrations or migrations from Google, Exchange, or other platforms, eMazzanti provides custom scoping and project management
How does eMazzanti ensure zero downtime during a Microsoft 365 migration for a business that cannot afford disruption?
eMazzanti achieves zero downtime through coexistence configuration — setting up mail flow between the source system and Microsoft 365 so that email is delivered correctly to both environments throughout the migration window. Users continue to send and receive email normally while their mailboxes are being migrated in the background. DNS cutover — the step that switches email routing entirely to Microsoft 365 — is scheduled and executed during low-traffic periods, typically over a weekend, and takes minutes to propagate. The migration is confirmed complete and user mailboxes are verified before the source server is decommissioned. Post-migration support for 90 days ensures that any issues surfacing after go-live are resolved quickly without the organization bearing that burden alone
