Microsoft 365 migration in Yuexiu

Microsoft 365 migration in Yuexiu is one of those projects that looks tidy in a plan and rarely stays that way. The first fork in the road is China-specific: stay on the global Microsoft tenant, or move to the 21Vianet-operated service? Everything afterwards — mail flow, Teams history, the audit trail your head office asks for — follows from that one decision.

NETK5 plans and runs Microsoft 365 migration work in Yuexiu for foreign-owned businesses: a pre-migration audit, tenant and licence review, the cutover itself, and the support in the weeks afterwards when the small problems surface. The worldwide tenant or the local service — that choice drives everything else.

What makes Microsoft 365 migration in Yuexiu a different project

People assume the global tenant and the China service differ only in where the servers sit. They don’t: licensing, feature behaviour and routing all vary, and performance is a function of how your traffic reaches Microsoft’s network. Layer the compliance question on top — what you may store where, and what you can demonstrate — and you have a design problem rather than a copy operation.

We audit before anyone touches a mailbox: licence entitlements, domains and DNS, mail flow rules, Teams and SharePoint usage, identity configuration, and which devices are enrolled where. Typical migrations take two to four weeks from audit to cutover.

What we migrate

• Mailboxes, mail flow and shared mailboxes
• Teams, channels and chat history, where the move allows it
• SharePoint and OneDrive content, with permissions checked before and after
• Identity — Entra ID, groups, authentication and conditional access
• Devices and policy, including Intune enrolment
• DNS records, domains, and the licence position on the new tenant

We move mailboxes first and collaboration content second, which keeps the team productive while the remainder follows.

How the project runs, step by step

1. Audit the current tenant and the actual business requirements
2. Design the destination — tenant choice, licensing, routing
3. Run a pilot group and record what actually changes for users
4. Cut over in a planned window; we schedule it outside business hours
5. Hypercare — we stay on for the fortnight after cutover, while the small faults surface
6. Hand over documentation, and support what we left behind

Where we work

We are not a single-city provider. NETK5 dispatches engineers across mainland China: our own team is based in Shanghai, Beijing, Guangzhou and Hong Kong, and we staff projects elsewhere in the country as clients need them — Xi’an, Chengdu, Taixing and beyond. Outside China we have delivered rack-and-stack work and WiFi surveys in Japan, Korea, Singapore and Taiwan, usually for international companies coordinating several sites from a head office that has never been on site.

For Microsoft 365 migration in Yuexiu that matters in a practical way: work can be planned around a visit rather than a relocation, and the same team that surveys or installs can hand over documentation the head office can actually use.

Our experience

Our China practice dates back to 2002 and Microsoft 365 work sits at its centre. We ran a pilot migration from the global tenant to 21Vianet for a client here, and we run cloud estates day to day — one of them more than thirty Azure virtual machines alongside Microsoft 365. Siemens, Nestlé, McKinsey and JLL are among the names we work with, generally alongside the international IT firms whose client sites we support.

The questions that come up every time

Do we have to move to 21Vianet if we are in China?

Not necessarily. Many foreign-owned companies stay on the global tenant quite happily; what you trade is performance, routing, and the ease of evidencing how data is handled. We also see the reverse, 21Vianet back to global, when a company restructures or exits. It depends on your users, your regulator and your head office — which is exactly why we audit first.

How long are users without email?

In a well-planned cutover, not at all in any meaningful sense: mail flow switches in a window and users sign in again afterwards. What takes time is the settling-in — profiles, devices, shared mailboxes, and the occasional Teams channel that behaves unexpectedly.

Can you support us after the migration?

Yes, and a good share of our migration work becomes ongoing support — helpdesk in English and Chinese, monitoring, and someone who already knows how your tenant was built.
