Office 365 migration in Changning
A Office 365 migration project in Changning looks simple on a spreadsheet and rarely stays that way. The first question is the one nobody asks outside China: the global Microsoft tenant, or the local 21Vianet service? From there it becomes a design exercise — keeping mail flowing, Teams history intact, and an audit trail your head office can actually read.
We run the whole sequence for foreign-owned companies in Changning: 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 Office 365 migration in Changning a different project
People assume the global tenant and the China service differ only in where the servers sit. They don’t: licensing, feature behaviour and routing all vary, and performance is a function of how your traffic reaches Microsoft’s network. Layer the compliance question on top — what you may store where, and what you can demonstrate — and you have a design problem rather than a copy operation.
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. Most migrations then take a few weeks to cutover.
The scope we move
- 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
- 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
- Settle the destination design: tenant, licensing, routing
- Run a pilot group and record what actually changes for users
- Cut over in a planned window; we schedule it outside business hours
- Hypercare — we stay on for hypercare, 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 Changning 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?
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.
