Our Microsoft 365 Plan
Migration Process
A structured and risk-free approach to ensure smooth, secure, and successful migration.
Discover & Plan
Audit your current environment — email platform, file storage, user accounts, and data volumes — to map exactly what needs to move, identify dependencies and risks, and build a migration plan with a clear timeline and zero-downtime approach tailored to your Irish business.
01.
02.
Design & Configure
Configure your Microsoft 365 tenant before migration begins — setting up user accounts, security policies, MFA, Exchange Online, SharePoint structure, and Teams — so your new environment is production-ready before a single piece of data moves across.
Deploy & Optimise
Execute the migration in controlled phases, moving emails, files, contacts, and calendars with full data integrity checks at every stage. Schedule cutover during low-impact hours to minimise disruption, and verify that all data has transferred correctly before decommissioning the source environment.
03.
04.
Train & Support
Brief your team on the new Microsoft 365 environment, provide hands-on guidance for daily workflows, and deliver post-migration support for the first 30 days so any issues are resolved quickly and adoption is solid from day one.
Frequently Asked Questions.
Find answers to common questions about Microsoft 365 migration and how MATA365 helps Irish businesses move from legacy systems, Google Workspace, or on-premise servers — without downtime, data loss, or compliance gaps.
How long does a Microsoft 365 migration take for an Irish business?
Every Mata365 Microsoft 365 migration includes a 30-day post-migration support period covering user issues, permissions problems, missing data queries, email delivery troubleshooting, and any configuration adjustments needed once your team is using the new environment in practice. We also provide a post-migration handover document covering the full configuration of your Microsoft 365 tenant — security settings, licences assigned, SharePoint structure, and admin credentials — so you have a clear record of your environment from day one.
Can MATA365 migrate our business from Google Workspace to Microsoft 365?
Yes. Google Workspace to Microsoft 365 is one of the most common migration paths MATA365 handles for Irish businesses. It involves migrating Gmail to Exchange Online, Google Drive content to OneDrive and SharePoint, Google Calendar to Outlook Calendar, and Google Contacts to Exchange contacts — with data integrity verified at each stage. DNS records are updated at cutover so the transition is seamless for your team and your clients. The migration is planned around your business hours so email access is not interrupted during the working day.
Will we experience downtime during our Microsoft 365 migration?
Zero downtime is the goal for every Mata365 migration. We use a staged migration approach where your new Microsoft 365 environment is fully configured and tested before any cutover happens. Email is the most sensitive element — we configure Exchange Online in parallel with your current mail system so both are running simultaneously during the migration window. Cutover to Microsoft 365 as the primary mail system typically happens overnight or over a weekend, and staff arrive on Monday with everything working in the new environment. Files and data are migrated progressively so there is no single point of disruption.
What happens to our data during a Microsoft 365 migration — is it GDPR compliant?
All data transferred during a Mata365 Microsoft 365 migration is handled in compliance with GDPR and Irish Data Protection Commission requirements. Data is transferred directly between your source system and Microsoft 365 — it is not stored on third-party servers in transit. Microsoft 365 data centres serving Ireland are located in the EU, ensuring data residency compliance. Mata365 documents the migration process, data flows, and post-migration configuration so you have a clear audit trail if required by your DPO or a regulatory review.
Can you migrate our existing files and SharePoint sites to a new Microsoft 365 tenant?
Yes. Tenant-to-tenant migration — moving from one Microsoft 365 environment to another — is a common requirement for Irish businesses following a merger, acquisition, or rebrand. It involves migrating mailboxes, OneDrive content, SharePoint sites, Teams channels, and user accounts between tenants while maintaining permissions and data integrity. This is one of the more technically complex migration types and requires careful planning to avoid disruption. Mata365 manages the full tenant-to-tenant migration process, including domain transfers and post-migration support.
