I run BIAB off the separate HD it came pre-installed on, and have virtually no space at all on my laptops internal drives. If I decide to upgrade to BIAB 2018, will I be able to use that same hard drive to reinstall over 2017?

Basically, I live in a country where import customs can are arbitrarily punitive and generally insane, and had to wait ages for a relative to come from the US to bring over the HD for BIAB 2017. Therefore, simply having a new HD shipped with 2017 is not a great option, especially as I have no idea when said relative will be coming again.

Note that I have the 2017 UltraPlusPAK, with the 49pak, and the hard drive I run it from still has 108 GB of empty space.
