Microsoft 365 migration in Wan Chai

Moving Microsoft 365 migration in Wan Chai is rarely a straight copy of mailboxes. For a company operating in China it starts with a decision most markets never face: whether your users should sit on the global Microsoft tenant or the local service operated by 21Vianet — and then how to move between the two without losing mail flow, Teams history, or the audit trail your head office expects.

For foreign-owned companies in Wan Chai we take the whole journey: audit, then tenant and licence design, then cutover, then the settling-in weeks when the odd fault surfaces. The aim is a migration nobody has to talk about afterwards.

Why Microsoft 365 migration in Wan Chai is not like migrating anywhere else

A global Microsoft 365 tenant and the China-operated service are not the same product with a different logo. Licensing differs, some services behave differently on each side, and performance depends on how traffic is routed between your offices and the nearest Microsoft edge. Add the compliance question — where personal data may legally sit, and what you can evidence to a regulator or a head office — and the migration becomes a design exercise, not a copy job.

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 a few weeks from audit to cutover.

The scope we move

• User and shared mailboxes, plus the mail-flow rules around them
• Teams and channels, carrying chat history across where the move supports 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
• Domains, DNS records and the licensing picture on the destination tenant

Exchange mailboxes move first, then the collaboration content, so people keep working while the rest follows.

How a migration runs

1. Establish what you have today against what the business genuinely needs
2. Design the destination — tenant choice, licensing, routing
3. Pilot with a small group and measure what really 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 Wan Chai 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?

It is a choice, not a requirement. Many foreign-owned companies stay on the global tenant and live with the trade-offs: performance, routing, and how easy it is to evidence how data is handled. We also handle moves the other way, from 21Vianet back to global, when a business restructures or exits. Your users, your regulator and your head office decide it, which is why the audit comes first.

How long are users without email?

Very little, if the cutover is planned properly: mail flow flips inside a window, users sign in again, work resumes. The time goes into the days afterwards — profiles, devices, shared mailboxes, and the odd Teams channel that behaves differently.

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.
