Official MSFT documentation does not answer this question directly so I decided to ask it here. Will VM migration from Windows 10 x64 (latest build/Anniversary update) to Server 2016 be possible? I don't speak about live migration (which is not supported by client Hyper-V) but wondering about some more convenient way of move all my VMs besides Import/Export function which will work assuming I have 2 host machines running side by side on the same network and can provide them with shared storage.
Your question isn't very clear. If you mean "Is there a way to put all the files that make up a VM somewhere that the Server 2016 host can use them as a VM" then that's "export." And, yes, it works. You can then import the exported VM.
If you exported it to the location that you want it to stay, you can do an in-place import that skips copying the VM again.
