A Microsoft 365 migration moves your email, files, calendars and collaboration onto the Microsoft cloud. Mycelium 365 delivers planned migrations for Australian SMEs with parallel co-existence, a fixed timeline, and no scheduled outage — your team keeps working through cutover, and every mailbox is validated before DNS flips.
Planned, low-risk Microsoft 365 deployment with clear cutover management for teams that cannot afford disruption.
Parallel co-existence means your team keeps working through the migration. No scheduled outage, no evening blackouts, no lost mail.
Every migration is scoped up front with a defined timeline, cutover date, and fixed price. No hourly billing surprises.
Entra ID, Conditional Access, MFA, Defender and Intune are configured as part of the migration — not a separate project six months later.
We migrate 5-user startups through to 250-user regulated SMEs across Melbourne, Sydney, Brisbane, Perth, Adelaide and Canberra.
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.
Structured cloud migration management from first discovery call to post-cutover hypercare.
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.
Domains, Entra ID, Conditional Access, MFA, Intune baselines, Defender for Office 365, SharePoint IA, and role-based licensing configured before any user data moves.
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.
DNS cutover at the agreed window, role-based enablement sessions, and 30 days of hypercare with daily check-ins and priority ticket handling.
Every workload from your current platform, mapped and moved into Microsoft 365 with data fidelity preserved.
Full mail history, calendar entries, resource mailboxes, distribution lists and contacts migrated to Exchange Online with metadata intact.
File shares, Google Drive and legacy SharePoint content moved to OneDrive and SharePoint document libraries with permissions preserved.
Teams, channels and shared workspaces stood up on the new tenant, with role-based training so users are productive on day one.
Entra ID Conditional Access, MFA, Defender for Office 365, and Intune device compliance configured as part of the migration — not bolted on after.
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.
