Begin with discovery
A successful migration starts with an inventory of mailboxes, shared mailboxes, file shares, permissions, applications and devices. This exposes old data, unsupported software and dependencies before they interrupt the move.
Design the destination
SharePoint, OneDrive and Teams serve different purposes. Recreating every old network drive in the cloud usually carries old problems into the new environment. Decide what should be personal, shared, archived or removed.
- Confirm domain ownership and Microsoft 365 licensing
- Design user groups and access permissions
- Plan identity, MFA and Conditional Access
- Choose a backup approach for Microsoft 365 data
- Prepare communication and user guidance
- Test migration batches before the final cutover
Plan for the day after migration
A migration is not complete when the data finishes copying. Staff need working applications, clear access, known support contacts and confidence that email and files are protected. ITSPLUS provides post-migration support and resolves issues as users settle into the new environment.
