Manual Upgrade Possible 4.3.10 - 4.4.1?

Hi,

I have been trying to upgrade via Upgrade Center, but getting problems with the process is timing out.

I have tried to clean logs, optimise DB etc...

Still it times out..

So it makes me think, is there a way to upgrade manually ?

upload new files via FTP etc ?

But how would I update the DB ?
