So, I have a subdomain foo.example.com, which is currently running on the same VPS as my root example.com. The subdomain is owned by a separate user, and now I want to move the subdomain to a new VPS. This is all very well and good, there’s even the “Move files to the new user” option.
However, the subdomain gets quite a bit of traffic. So I have a few questions:
Does “move” mean “copy” or will this remove the files from the old user?
How long will it take to move all the files?
Does the switch happen immediately after all of the files have been moved?
Will the site be down at any point, and if so, for how long?
[*]Is there any way to move the user as well, rather than creating a new user with a different name?
My final question is: To avoid any unknowns, would it be worth my time to just create a new user, move (copy) everything myself and then change the subdomain to point to the new user?
