Migrations we handle
Most Microsoft 365 work falls into a handful of shapes. Each has its own risks, and the planning differs more than the tooling does.
Tenant-to-tenant migrations
Moving users, mailboxes, files and Teams content from one Microsoft 365 tenant into another. This is the one that usually arrives with a deadline attached — an acquisition completing, a demerger separating two halves of a business, a rebrand onto a new domain, or an exit from a provider who holds the tenant on your behalf.
It is more demanding than a first-time migration because both environments are live and in use. Identity, licensing and mail flow all have to be sequenced so nobody is locked out mid-transition.

On-premises Exchange to Microsoft 365
Retiring an Exchange server and moving mail into the cloud, including the public folders and shared mailboxes that tend to surface late in the process. We keep the old environment intact until the new one is confirmed working.
Google Workspace to Microsoft 365
Gmail, Drive, shared drives and calendars moved across. The decisions that matter get made before data moves: how Google Docs formats convert to Office formats, and what happens to the sharing links people have already circulated.
File shares and SharePoint
Mapped drives and ageing file servers into SharePoint and OneDrive, with a permissions structure that reflects how the business actually works rather than replicating twenty years of accumulated folder sprawl.
How a migration runs
- DiscoveryMailbox sizes, data volumes, licensing, domains, devices, and the integrations nobody remembers until they break — line-of-business apps sending mail, scan-to-email on the copier, shared calendars.
- Plan and pilotA migration plan with a cutover window, then a small pilot group moved first. The pilot is where surprises surface cheaply, while it is still a handful of people rather than everyone.
- Pre-stage the dataMail and files synchronised to the destination ahead of time, so cutover moves a small delta rather than everything at once. This is why a well-run cutover is short.
- CutoverUsually outside business hours. Mail routing switches, final delta syncs, clients reconfigure. Mail sent during the switch queues at the sending server and delivers once DNS propagates.
- AftercareThe first week is when the real questions arrive. Signatures, mobile devices, that one shared mailbox nobody mentioned. We stay close through it rather than handing over and disappearing.
Beyond the migration
A migration is a project with an end date. What follows is the part that determines whether Microsoft 365 is actually working for you.
- Administration and optimisation — tenant configuration, mail flow rules, shared mailboxes and groups, and cleaning up the settings that accumulate over time
- Licence review — matching licences to what people actually use. Over-licensing is common and quietly expensive; under-licensing shows up as features that mysteriously do not work
- Security baseline — multi-factor authentication, conditional access, and sensible defaults, configured so security does not become the thing everyone works around
- Ongoing support — a point of contact who already knows how your tenant is configured
Common questions
How long does a Microsoft 365 migration take?
For a small business of 5 to 50 users, most migrations run over two to four weeks from discovery to cutover. Mailbox count matters less than data volume and how much archive history has to move. Large file shares and long-lived SharePoint sites are usually what extends a timeline.
Will we lose email during the migration?
No. Mail is synchronised to the destination before cutover, so both environments hold the data while the change is made. Cutover is normally scheduled outside business hours, and mail sent during the switch queues at the sending server and delivers once DNS updates.
What is a tenant-to-tenant migration?
Moving users, mailboxes, files and Teams content from one Microsoft 365 tenant to another. It comes up after an acquisition, a demerger, a rebrand onto a new domain, or when leaving a managed provider who holds the tenant. It is more involved than a first-time migration because both sides are live.
Can you migrate from Google Workspace to Microsoft 365?
Yes. Gmail, Google Drive, shared drives and calendars all move across. The main planning points are how Google Docs formats are converted to Office formats and how existing sharing links are handled — both decided before any data moves.
Do we need to be in Sydney to work with you?
No. Migration work is delivered remotely, so we work with businesses across Australia. We attend on-site across Greater Sydney, including Parramatta, Westmead, Northmead, Auburn, Wetherill Park, Liverpool, Bankstown, Oran Park and North Sydney.
