M365 backup in Foshan

M365 backup in Foshan 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.

For foreign-owned companies in Foshan 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 M365 backup in Foshan 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.

The audit comes before any mailbox is touched: licences, domains and DNS, mail rules, how Teams and SharePoint are genuinely used, identity configuration, and which devices are enrolled where. Typical migrations then take a few weeks to cutover.

What we migrate

• Mailboxes, mail flow and shared mailboxes
• 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

Mailboxes go first and collaboration content follows, so the team keeps working while the rest of the estate catches up.

How the project runs, step by step

1. Audit the current tenant and the actual business requirements
2. Settle the destination design: tenant, 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 for a weekend
5. Hypercare — we stay on for hypercare, 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 M365 backup in Foshan 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 before

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?

No. Plenty of foreign-owned companies run on the global tenant and it works. The trade-offs are performance, routing, and how comfortably you can evidence data handling. Some migrations go the other way — from 21Vianet back to global — when a company restructures or leaves. The right answer depends on your users, your regulator and your head office, 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.
