Why SMEs choose Mycelium 365 for M365 migration
Planned, low-risk Microsoft 365 deployment with clear cutover management for teams that cannot afford disruption.
Zero-downtime by design
Parallel co-existence means your team keeps working through the migration. No scheduled outage, no evening blackouts, no lost mail.
Fixed timeline, fixed price
Every migration is scoped up front with a defined timeline, cutover date, and fixed price. No hourly billing surprises.
Security baked in
Entra ID, Conditional Access, MFA, Defender and Intune are configured as part of the migration — not a separate project six months later.
Australian SME specialists
We migrate 5-user startups through to 250-user regulated SMEs across Melbourne, Sydney, Brisbane, Perth, Adelaide and Canberra.
What is included in a Mycelium 365 Microsoft 365 migration?
Every migration is scoped as a fixed-price, fixed-timeline project. You know the cutover date, the inclusions and the price before any work begins — and your team keeps working the entire time.
Our four-phase migration process
Structured cloud migration management from first discovery call to post-cutover hypercare.
Discovery & Planning
User inventory, mailbox sizing, file footprint, shared drive mapping, calendar and app dependency audit. You receive a fixed migration plan with timeline and cutover date.
Tenant Preparation
Domains, Entra ID, Conditional Access, MFA, Intune baselines, Defender for Office 365, SharePoint IA, and role-based licensing configured before any user data moves.
Wave Migration
Mailboxes, calendars, contacts and files migrated in validated waves with parallel co-existence — users keep working on the source platform until their wave is cut over.
Cutover & Hypercare
DNS cutover at the agreed window, role-based enablement sessions, and 30 days of hypercare with daily check-ins and priority ticket handling.
What we migrate
Every workload from your current platform, mapped and moved into Microsoft 365 with data fidelity preserved.
Email, Calendars & Contacts
Full mail history, calendar entries, resource mailboxes, distribution lists and contacts migrated to Exchange Online with metadata intact.
Files to OneDrive & SharePoint
File shares, Google Drive and legacy SharePoint content moved to OneDrive and SharePoint document libraries with permissions preserved.
Teams & Collaboration
Teams, channels and shared workspaces stood up on the new tenant, with role-based training so users are productive on day one.
Security & Compliance
Entra ID Conditional Access, MFA, Defender for Office 365, and Intune device compliance configured as part of the migration — not bolted on after.
IT migration planning built for Australian SMEs
Most SME Microsoft 365 migration failures come from the same three things: no discovery, no co-existence, and no post-cutover support. Mycelium 365 removes all three. Discovery maps every mailbox, calendar, shared drive and integration before we quote — so the scope is real, not aspirational. Co-existence keeps mail flowing between your source platform and Exchange Online during the migration window, so there is never a period where users cannot send or receive. And 30 days of hypercare means your team is not on their own the day after cutover.
Whether you are moving 15 users off Google Workspace, 80 users off on-prem Exchange, or consolidating two Microsoft 365 tenants after an acquisition, the same disciplined process applies — with the toolset and phasing tuned to your environment. Every project is delivered by Australian-based engineers, with data residency held in Microsoft's Australia East and Australia Southeast regions throughout.
Google Workspace to Microsoft 365 Migration
Moving off Google Workspace is the most common migration we run. Mycelium 365 migrates Gmail to Exchange Online, Google Drive to SharePoint and OneDrive, Google Calendar to Outlook Calendar, and Google Contacts to Exchange contacts — with labels, folders, sharing permissions and version history mapped across so nothing is lost in translation.
Every Google Workspace migration is delivered as a fixed-price project with a parallel-run period: mail flows to both platforms while we verify every mailbox and file, and users keep working until the cutover is confirmed clean. Zero email downtime, no lost data, no big-bang risk.
