M365 migration in Panyu
A M365 migration project in Panyu 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 Panyu: 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.
Why M365 migration in Panyu is not like migrating anywhere else
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.
Nobody touches a mailbox until the audit is done: what you are licensed for, how Domains and DNS are set, which mail rules exist, how Teams and SharePoint are genuinely used, how identity is configured, and where the devices are enrolled. Most migrations take two to four weeks end to end.
The scope we move
- 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
- Identity — Entra ID, groups, authentication and conditional access
- Devices and policy, including Intune enrolment
- DNS records, domains, and the licence position on the new tenant
We move mailboxes first and collaboration content second, which keeps the team productive while the remainder follows.
How a migration runs
- Establish what you have today against what the business genuinely needs
- 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 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 M365 migration in Panyu 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 beforeWe 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.
The questions that come up every time
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?
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.
