Microsoft 365 and Azure migrations for organisations — Google Workspace, on-premises Exchange, file servers and legacy infrastructure moved with security, governance and adoption built in from day one.
Cloud migration is the disciplined move of email, files, identity, applications and infrastructure from legacy or competitor platforms onto Microsoft 365 and Azure — done in a way that preserves data integrity, keeps users productive through cutover, and meets Australian data-residency requirements. For organisations the why is rarely just cost; it's security posture, hybrid-work resilience, compliance evidence and the ability to actually use Microsoft 365's security and AI stack. Mycelium 365 specialises in pragmatic, risk-managed migrations with a fixed-price scope and a real hypercare period — not a hand-off that ends at cutover.
Who this is for
organisations moving off Google Workspace, on-prem Exchange, file servers, Citrix or legacy hosted email, and businesses lifting on-prem servers into Azure. Particularly suited to regulated industries (legal, finance, healthcare, defence supply chain) where data sovereignty and audit evidence matter, and to mid-sized businesses (25–500 users) where a botched migration would meaningfully disrupt operations.
Why Migrate to Microsoft 365?
Reduce Costs
Eliminate on-premises server hardware, licensing, and maintenance costs with predictable monthly subscriptions.
Enhance Security
Leverage Microsoft's enterprise-grade security with Defender, Conditional Access, and Zero Trust architecture.
Enable Remote Work
Give your team secure access to email, files, and collaboration tools from anywhere on any device.
Migration Services We Offer
Google Workspace to Microsoft 365
Complete Gmail → Outlook, Google Drive → OneDrive/SharePoint, and Google Meet → Teams migration. Mailbox data, calendars, shared drives, permissions and aliases are preserved, with coexistence mail flow during cutover so nothing bounces. Most 25–100-user moves complete inside a fortnight.
On-Premises to Microsoft 365
Legacy on-prem Exchange (2013/2016/2019), file servers and Active Directory migrated into Exchange Online, SharePoint/OneDrive and Entra ID. Hybrid configurations supported throughout so you cut over at your pace rather than in a big-bang. Identity becomes cloud-authoritative with Entra Connect handling sync until you're ready to retire on-prem AD.
SharePoint & File Server Migration
File shares, NAS, Dropbox and Google Drive structures mapped to a proper SharePoint information architecture (not just lifted into folders), with metadata, modified dates and permissions preserved where possible. We pilot with one business unit before cutting over the rest, so problems are caught at small scale.
Microsoft Teams Deployment
Teams rolled out with proper governance from day one — naming conventions, channel and team templates, external access controls, sensitivity labels, and integration with line-of-business apps. We avoid the sprawl that turns Teams into 400 abandoned channels inside six months.
Azure Cloud Migration
Lift-and-shift, re-platform or re-architect server workloads into Azure landing zones in Australia East and Australia Southeast. Discovery, dependency mapping, Azure Migrate assessment, cutover and hand-off into ongoing subscription management — with data sovereignty enforced via Azure Policy.
Business Email Migration
Migrate from any source platform (cPanel/IMAP, hosted Exchange, Zimbra, MDaemon, Lotus Notes, Google) into Exchange Online with calendar, contacts, rules, delegations and shared mailboxes fully preserved. SPF, DKIM and DMARC are reconfigured properly on cutover so deliverability improves rather than degrades.
Our Migration Process
Discovery & Assessment
Audit your current environment — mailboxes, files, identities, devices, apps and integrations — and map dependencies. The output is a detailed migration design with risk register, cutover plan and fixed-price quote.
Planning & Design
Architect the target Microsoft 365 or Azure environment with Australian data residency, Conditional Access, retention, backup and governance built in from the start rather than bolted on after.
Pilot Migration
Migrate a small, representative user group (typically 5–10 users) and use the new environment in anger for 1–2 weeks. Issues surface at small scale where they're cheap to fix, and the pilot group becomes internal champions for the wider rollout.
Production Cutover
Execute the migration in planned batches — usually evenings and weekends — with mail coexistence and incremental sync so nothing bounces and no work is lost. Communication to users runs in parallel so they know exactly what changes on Monday morning.
Validation & Hypercare
Data integrity, mail flow, permissions and adoption verified, training delivered, and a 2–4 week elevated-support hypercare period before transitioning to steady-state managed services. We don't disappear the day after cutover.
