Frequently Asked Questions — Microsoft 365 Migration
How long does a Microsoft 365 migration take?
Migration timelines depend on the size and complexity of your environment. Small businesses with fewer than 20 mailboxes can typically migrate in one to two days. Larger organisations with complex on-premises infrastructure may require several weeks for a staged migration. Cloud Solution IT provides a detailed timeline after the pre-migration assessment.
Will users lose any email or files during migration?
When managed by Cloud Solution IT (CSIT), the risk of data loss is effectively zero. We use proven migration toolsets and perform multi-stage validation to confirm all data is present and correct before cutover. We also maintain your source environment until the migration is fully verified.
Do we need to do anything before the migration?
CSIT handles all pre-migration preparation, including environment audits, licence provisioning, and DNS configuration. Users may be asked to clear out old items or archive large amounts of historical data, but our team will guide you through any required actions.
Can you migrate from Exchange 2010 or earlier?
Yes. We support migrations from Exchange 2010, 2013, 2016, and 2019. For very old versions, we may recommend an intermediate migration step, which our team will explain clearly during the assessment phase.
