Office 365 migration in Xi'an
Moving Office 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.

NETK5 plans and runs Office 365 migration work in Xi'an 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. Global tenant or 21Vianet — that choice drives everything else.
What makes Office 365 migration in Xi'an a different project
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. A straightforward tenant move take two to four weeks from audit to cutover.
What we migrate
- User and shared mailboxes, plus the mail-flow rules around them
- Teams, channels and chat history, where the move allows it
- SharePoint and OneDrive content, with permissions verified on both sides
- Entra ID, groups, sign-in policy and conditional access
- Endpoint policy and Intune device 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
- Establish what you have today against what the business genuinely needs
- Settle the destination design: tenant, 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 Office 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 experienceWe 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?
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?
With a properly planned cutover, barely: mail flow switches inside a window and everyone signs back in. The slow part is the settling-in — profiles, devices, shared mailboxes, and the occasional Teams channel that surprises you.
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.
