But if I download the iso and want to install it, it doesn't allow me to keep the configuration and files. This option appears disabled (see image). My server is in a datacenter and I access it remotely.

You need to run setup.exe from the mounted ISO from within Windows. If you boot to the ISO, you can't do the upgrade.
If by chance you are running setup.exe from the mounted ISO within Windows, then something else is blocking it.
