Microsoft 365 Migration With Everything Working From Day One
The decision to move to Microsoft 365 is usually straightforward. The migration itself is where complexity enters the picture.
Exchange Online has specific provisioning requirements that differ from other email platforms. SharePoint and OneDrive have permission models that do not map cleanly onto most other file storage systems. Teams requires deliberate configuration to reflect how your organisation actually communicates. And all of it needs to be sequenced correctly, with DNS changes timed precisely, to avoid disruption to a business that depends on these tools every day.
Yeevu manages Microsoft 365 migrations end to end. We handle the planning, data transfer, DNS configuration, platform setup, and staff onboarding so your business lands in Microsoft 365 with everything working and nothing unresolved.
01
Who This Service Is For
- Businesses migrating from Google Workspace who want the compliance capabilities, Office application integration, and Windows ecosystem alignment that Microsoft 365 provides, and need their email, calendar, and file data transferred without gaps.
- Businesses moving off on-premise Exchange Server where the infrastructure cost, maintenance burden, and limitations of a self-hosted mail server have reached the point where cloud migration is the right move.
- Businesses leaving legacy hosting email such as cPanel, Zoho Mail, or registrar-provided email, where the reliability, security, and functionality of the current setup no longer meet business requirements.
- Professional services firms, legal practices, and regulated businesses that need the compliance, data governance, and eDiscovery capabilities of Microsoft 365 and want the platform configured correctly to meet those requirements from day one.
- Businesses consolidating multiple tools onto a single platform, replacing a combination of standalone email, file storage, video conferencing, and communication tools with the integrated Microsoft 365 environment.
- Businesses that started a self-managed migration that ran into problems and need an expert to assess the situation, resolve what went wrong, and complete the migration properly.
02
What We Handle
Pre-Migration Audit and Planning
Full documentation of every mailbox, shared mailbox, distribution group, calendar resource, and file repository in scope. Data volumes, source platform characteristics, compliance requirements, and business continuity considerations all factored into the migration plan before anything moves.
Microsoft 365 Tenant Setup
Tenant provisioned and configured to your specific requirements – security settings, domain configuration, conditional access policies, and administrative structure – before migration begins.
Domain Verification and DNS Preparation
Domain verified with Microsoft 365. All required DNS records prepared. MX and Autodiscover record TTL values reduced in advance to minimise the cutover window.
User Provisioning and Licence Assignment
Every account created, licences assigned, multi-factor authentication configured, and aliases set up. Address mapping documented across the full user base where email addresses are changing.
Exchange Online Mailbox Migration
Email migrated from the source platform to the correct Exchange Online accounts. Shared mailboxes provisioned separately. Distribution groups and mail-enabled security groups recreated. Progress monitored throughout and validated before cutover.
Calendar and Contact Migration
Calendar events migrated with attention to recurring event accuracy. Room and resource mailboxes configured in Exchange Online. Contacts and shared address books migrated and accessible.
SharePoint and OneDrive Setup and File Migration
SharePoint site structure and OneDrive configuration designed before migration begins. Files migrated with folder hierarchy preserved and permissions reviewed and reconfigured for the Microsoft 365 environment.
Microsoft Teams Configuration
Team and channel structure aligned to your organisational units or project workflows. Guest access, meeting policies, and Microsoft 365 service integrations configured. We ensure that Teams is set up as a working environment.
MX Record Cutover
Timed for a low-traffic window. Both environments monitored throughout propagation. Routing issues identified and resolved in real time. Cutover not complete until email is confirmed routing correctly to Exchange Online.
Email Authentication Configuration
SPF, DKIM, and DMARC configured and validated for the Exchange Online environment before sign-off.
Staff Onboarding and Access Verification
Every user confirmed operational across Outlook, OneDrive, SharePoint, and Teams before the engagement closes.
Post-Migration Validation and Report
We run a structured validation process covering every component of the migration once all data transfer and configuration work is complete. We produce a post-migration report documenting what was migrated, any issues encountered and how they were resolved, the current configuration of DNS records and email authentication, and any recommended follow-up actions or ongoing management considerations.

Our Microsoft 365 Migration Process
- Audit, Planning, and Tenant Setup Discovery call and existing environment audit. Migration planning document produced and agreed. Microsoft 365 tenant provisioned and configured. Domain verification and DNS preparation including TTL reduction on MX and Autodiscover records. User accounts provisioned and licences assigned.
- Data Migration Exchange Online mailbox migration running in the background while the existing email platform remains live. Calendar and contact migration. SharePoint and OneDrive setup and file migration from existing storage. Teams configuration. Ongoing monitoring of migration progress and resolution of any issues encountered.
- Pre-Cutover Validation Validation of migrated mailbox data, calendar events, contacts, and files in the new environment. DNS record review and confirmation that all Microsoft 365 authentication records are ready. Staff access testing in the new environment before the cutover is initiated.
- MX Record Cutover and Go-Live MX record cutover timed for a low-traffic window. Monitoring of both environments throughout propagation. Confirmation of correct email routing to Exchange Online. SPF, DKIM, and DMARC finalisation and validation.
- Staff Onboarding and Post-Migration Validation User onboarding sessions covering Outlook, OneDrive, SharePoint, and Teams. Access verification for every user. Post-migration validation sweep and report delivery.
05
Timeline
One to four weeks depending on data volume, number of users, source platform complexity, and compliance requirements. Larger or more complex migrations are scoped individually following the audit.

Why Businesses Choose Yeevu for Microsoft 365 Migration
We understand the full scope of what a Microsoft 365 migration involves.
Exchange Online, SharePoint, OneDrive, and Teams each have their own migration considerations and configuration requirements. We address all of them, not just the email component that most businesses think of first.
We treat SharePoint and OneDrive permissions seriously.
File permission migration is where Microsoft 365 migrations most frequently create post-migration remediation work. We assess the permission structure of your existing environment before migration begins and configure the Microsoft 365 file storage environment to reflect it correctly.
We configure Teams as a working environment, not just an installed product.
Teams that is set up but not used represents real money spent on licences that deliver no value. We configure Teams to match how your organisation actually works, and we include it in staff onboarding so your team understands how to use it from day one.
We handle DNS with the same precision we apply to every DNS engagement.
Every record change required for a Microsoft 365 migration is made in the correct sequence, at the right time, and validated before the next step proceeds. Email authentication records are configured completely, not just the MX record.
We stay involved until every user is confirmed to be working.
The migration is not complete when the data transfer is done. It is complete when every member of your team can access their email, find their files, use their calendar, and operate in Teams without issue. That is the standard we hold ourselves to.

Frequently Asked Questions
How long does a Microsoft 365 migration take?
Most migrations are completed within one to four weeks. The timeline depends on data volume, number of users, the source platform being migrated from, and any specific compliance or configuration requirements. We provide a specific timeline estimate following the pre-migration audit.
Will there be any disruption to email during the migration?
Email migration runs in the background while your existing platform remains live. The MX record cutover is the only period of potential disruption, and we manage it with precision to keep the transition window as short as possible.
Can you migrate from Google Workspace to Microsoft 365?
Yes. This is one of the most common migrations we handle — covering Gmail to Exchange Online, Google Calendar to Outlook Calendar, Google Contacts to Outlook Contacts, and Google Drive to SharePoint and OneDrive.
Can you migrate from on-premise Exchange Server?
Yes. The specific migration approach depends on the Exchange Server version in use, which we assess during the pre-migration audit.
Can you configure Microsoft 365 for compliance requirements?
Yes. Retention policies, eDiscovery, data loss prevention, and audit logging are configured as part of the tenant setup for businesses with regulatory requirements.
Do you handle SharePoint configuration as well as file migration?
Yes. SharePoint setup, site structure design, document library configuration, and permission management are included in the engagement scope alongside the file migration itself. We do not simply copy files into an unconfigured SharePoint environment.
What if our existing setup is complicated or poorly documented?
The pre-migration audit is specifically designed to produce a clear picture of the existing environment regardless of how well it was previously documented.
What happens to emails sent during the MX record cutover?
We manage the cutover to minimise the window during which DNS changes are propagating. By reducing MX record TTL values in advance, we ensure that most resolvers pick up the change quickly. Both the old environment and Exchange Online are monitored throughout the propagation period, and any email routed to the old environment after the cutover is initiated is identified and handled.
Can you configure Microsoft 365 for compliance and data governance requirements?
Yes. For businesses in regulated industries, we configure Microsoft 365 compliance features including retention policies, eDiscovery settings, data loss prevention policies, and audit logging as part of the tenant setup. Specific compliance requirements are discussed and scoped during the pre-migration audit.
Ready to Move to Microsoft 365 the Right Way?
Whether you are migrating from Google Workspace, moving off an ageing Exchange Server, or leaving a legacy hosting platform behind, we are ready to help you make the move without disruption.
