If you have a working internal installation and FOSS bootloader, you don't need any .iso to install or upgrade. I rarely install from any iso, OM or USB. You can download the installation kernel and initrd and load them with your existing bootloader. The installer will then download only the packages to be installed. There are similar other options that require minimal or no downloading in advance of installation:
