Microsoft 365 migration in Yuexiu
Moving Microsoft 365 migration in Yuexiu 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.
We run the whole sequence for foreign-owned companies in Yuexiu: audit first, then tenant and licence design, then the cutover, then the weeks of settling-in while the small faults surface. Nobody enjoys a migration; the job is to make it unremarkable.
Why Microsoft 365 migration in Yuexiu is not like migrating anywhere else
Treat the two clouds as different products, because that is what they are. Licences differ, some features behave differently, and performance comes down to how traffic leaves your office and where it joins Microsoft’s network. Then there is the compliance angle: where personal data may legally sit, and what you can hand to a regulator or a head office when they ask.
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.
What we migrate
- 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
Mailboxes go first and collaboration content follows, so the team keeps working while the rest of the estate catches up.
How a migration runs
- Audit the current tenant and the actual business requirements
- Design the destination — tenant choice, licensing, routing
- Pilot with a small group and measure what really changes for users
- Cut over in a planned window; we schedule it outside business hours
- Hypercare — we stay on for the fortnight after cutover, while the small faults surface
- 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.
Where we have done this beforeOur 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.
Questions we get asked
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?
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.
