Microsoft 365 migration in Xi'an

Moving Microsoft 365 migration in Xi'an 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 Xi'an: 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.

What makes Microsoft 365 migration in Xi'an a different project

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. Most 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
• Entra ID, groups, sign-in policy 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 the project runs, step by step

1. Establish what you have today against what the business genuinely needs
2. Settle the destination design: tenant, licensing, routing
3. Run a pilot group and record what actually changes for users
4. Cut over in a planned window; we schedule it for a weekend
5. Hypercare — we stay on through the settling-in period, while the small faults surface
6. Leave you with documentation, and keep supporting the estate afterwards

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 Xi'an 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

We have supported international businesses in China since 2002, and Microsoft 365 is at the centre of nearly all of it. That includes a pilot migration from the global tenant to 21Vianet for a client operating in China, and the ongoing management of cloud estates — among them more than thirty Azure virtual machines running alongside Microsoft 365. Siemens, Nestlé, McKinsey and JLL are among the names we work with, typically alongside the international IT companies whose client sites we support.

Questions we get asked

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.
