M365 backup in Hongqiao
M365 backup in Hongqiao 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.
NETK5 plans and runs M365 backup work in Hongqiao 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 the local service — that choice drives everything else.
What makes M365 backup in Hongqiao 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. 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, channels and chat history, where the move allows it
- SharePoint and OneDrive content, with permissions checked before and after
- 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 move first, then the collaboration content, so people keep working while the rest follows.
How the project runs, step by step
- Audit the current tenant and the actual business requirements
- Design the destination — tenant choice, licensing, routing
- Run a pilot group and record what actually changes for users
- Cut over in a planned window; we schedule it for a weekend
- Hypercare — we stay on through the settling-in period, while the small faults surface
- 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 M365 backup in Hongqiao 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 beforeSince 2002 we have looked after IT for international companies in China, and Microsoft 365 sits at the centre of most of it. We have run a pilot migration of Microsoft 365 from the global tenant to 21Vianet for a client operating in China, and we manage cloud estates day to day — including an environment of more than thirty Azure virtual machines with Microsoft 365 alongside it. Our clients include names such as Siemens, Nestlé, McKinsey and JLL, usually 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?
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.
