Just ordered the 2023 UltraPAK upgrade in HD (which also comes with electronic install).

Now, if the UltraPAK will just write over my 2022 MegaPAK, but I only have 100 GB
left on my desktop's HD, will the electronic install stop at some point and tell me there's not enough space, or will the UltraPAK just write over the MegaPAK and cover it?
